Valkyrie hasn’t failed. Mine sure hasn’t. Shooting 80 gr Sierra Mk and cfe223 I get sub moa at 300 yards easy. Valkyrie is a reloaders dream. But I’m with most others...I’ll stay with my Grendel.
What didn’t it deliver?? I have folks shooting their 85 and 90 bullets sub moa out of The Valkyrie out to 1000 plus yards!! How’s that a fail? That’s what it is supposed to be doing. It takes work to get it there, but that’s the beauty of things. Anything worth having you have to work for. But hey your opinion is yours. I beg to differ and that’s my right. Out.
@Nick Rodriguez the Valkyrie performs better than any AR15 round at distance. As for AR10 which is a totally different platform (whole new gun) it performs better than 308 in everything but energy on target and comes close to 6.5 CM on everything but energy. If you want a lighter weight long range AR15 that can hit at incredible range Valkyrie does it.
@@aspenair8988 That might have been true aerodynamical technology in bullets has come leaps and bounds in the past 10yrs. In 1993 243cal bullets sucked.
308's an old glue horse.I heard there were free 308 barrels in dumpsters behind SOCOM armories nationwide since they've dropped 308 for 6.5cm. New calibers > old calibers
I just put together a palmetto 20" Grendel and am more than happy with the results. I did put a larue mbt2s trigger in it right off the bat and am meticulous on barrel break in (my own deal there). 100 yard 5 shot groups with Wolf ammo I can cover with my thumb. So 3/4 to 1 inch. I'm happy.
That's my thing on grendel, when want to do the weekend thing have option of cheap ammo like wolf steel you mention. Just curious what you think of the larue for setup. Was going to buy one for build wanting to do
@@kotaboy32 yeah, would love to see that too. better yet, vids of it, real time. got 2 6.5Gs an shot lots of wolf. Can easily do that +, with hornady 123gr sst handloads. wolf, not so much.
I have 2 AR15 Grendels and a howa bolt. None of them shoot wolf well at all. I have shot 1/2 inch groups with my 123SST IMR4895 loads, but wolf shoots about 2 inch groups.
The 6mm ARC would be cool if you could actually find readily available ammo in stock at a price you can afford to shoot like Wolf or Barnaul 6.5 Grendel.
@@issstari954 Yes there's some Hornady 108gr ELD for $1.57/round. It was running $1/round before the shortage so that's about on par with the rest of the ammo market right now. Use ammoseek to find ammo that's what everyone else does.
I've been really interested in this exact comparison. This idea of squeezing basicly a .243 into an AR-15 platform could be a game changer. Thank you for the info.
The 6 looks good, but still uses the Grendel case. With people still having pressure issues breaking bolts, is this going to now transfer to the ARC? I’m pretty well invested in the 6.8 as it is, and the problem I see with all of these -15 cartridges is they are unable to get the kinetic energy to justify their use at ranges past 4-600yds for anything other than pinching paper. It just seems to be the limitation of the casing. I wish the development of the arc utilized a casing a little more forgiving in an AR-15 platform. I’ll keep up to date with the progress, but will likely stick with the 6.8 that is highly effective at practical ranges for the platform and utilizing a case less prone to parts breakages. Thanks for the vid
the grendel bolts issue was on people's lips 10 years ago. Now a days people make bolts even thinner than for the Grendel, like the POF revolution: a 308 bolt for an AR15 sized carrier (some bolt diameter as .223 but with a .308 case head cut out, very thin side walls). The Grendel bolt issue wasn't a problem with the grendel. It was a metallurgy issue.
The type two bolt I am using in one of my 6.5 Grendel AR;s has 2k rounds without a problem and my loads are only a grain or two from max. That problem was cured by Alexander Arms a few years ago. Load correctly, set up your chamber, barrel torque and head spacing , and you should have no problems.
The advantage for 6.5 grendel to me is rifle weight. The .308 iis a much heavier platform. The 6.5 allows a slightly bigger bullet in the 123 over the arcs 108 . The differencs isnt much but still for my hunting needs the grendel seems to work . For punching holes in paper the arc might be the better choice.
that's respectable... picked up my barrel at my local manufacturer for $100 and a upper-lower combo for the same price and that's what started it for me. I've started buying wolf 6.5 Grendel at 50c a shot so we'll see how it works out!
I just bought a box of 500 6.5 Grendel from Wolf because it's becoming rare. I don't even have the rifle built yet, but I wanted some inexpensive ammo for zeroing and plinking. I'd hop on inexpensive ammo if you can afford it. For me, I went with the 6.5 Grendel because it is more available and I am not shooting past 500 yards because this will be a deer hunting rig. No reason to pay twice as much for 6mm ARC ammo, barrels and parts.
I built my own AR-15 chambered in the 6mm ARC and have less than $500 in it right now. first group with Hornady black was .75 inches. 24" stainless barrel so I can get most all the velocity that the cartridge offers in a bolt gun.
I Have 3 ARC’s However My 6.5 PRC Holds & Delivers Over A 600 BC Which Is The Most Important In Ballistic Co-Efficiency. Great Footage. Keep It Coming. Both Are Good For Over 1200 Yards With Excellent Optics. Especially The 6.5 PRC’s.
Hornady plays games using different barrel lengths and bullets then comparing. The 22arc is a prime example. When you look at the reloading data, the 224 valk. Is equal/better than 22 arc. The 6.8spc is tested with a 16" barrel while most other rounds are tested with a 24" barrel. 8 inches of barrel (200 fps) makes a difference.
I shoot both the 6.5 Grendel and the 6MM ARC. Both of them are awesome rounds. I chambered the 6.5 Grendel in an 18 inch barrel and the 6 MM ARC out of a 20’ inch barrel. Using them both for different purposes. 6.5 Grendel for camping and the 6 ARC for competition shooting. These rounds were very hard to find during the Plandemic and I ended up finding a plug at the gunshows and he would sell both ballistics in bulk. It was expensive but worth it at the time. Now I can find 6MM ARC easily but the Grendel is still pretty illusive as it isn’t found in as many places as the 6 MM ARC.
Honestly the Grendell was originally conceived for Army special forces to be able to target longer distance targets with the shorter rifle chanbered in 14" most of the time and have more penetrating power even than the .223 round they carry now. 6mm is awesome however.
Well, it’s also nice when he’ll put on some add where he stumbles through it and sounds just like trump says he does. Trump can’t buy advertising that good
F.Y.I. I'm getting 2250 fps out of 123's with my 12" 6.5 Grendel reloading using Benchmark powder. Can't jive with him saying he only getting another 100 fps with another 8" of Barrel length Specially with my buddy getting 2500 fps in his 18" . Don't know why these guys gotta fudge the #'s
You're gonna love that pistol chambered in Grendel. I finished an Alexander Arms 11.5" pistol build earlier this year. Slapped a Razor gen 3 1-10 on it and its the closest I've come to a true do it all build. It is the absolute pride and joy of my collection. From cqb all the way out to 1000, it gets the job done.
Something looks off. A 123gr 6.5 Grendel projectile out of an 18 inch barrel should still be supersonic past 1,000 yards. And a 168gr projectile in a 308Win is NOT supersonic at 1,000 yards. A 175gr will be, but not the 168.
Honestly logistics was the major factor in steering me toward 6 ARC. Uses small primers, powders I already keep on hand for 223, selection of bullets out the wa-zoo. Everything needed to make a quality bullet is a lot easier and cheaper to get when you can find it. Couple that with a excellent range the bullet stays supersonic at and it was a no brainer.
I bought all the upper parts for a 264LBC (6.5 grendel) the day before Hornady released all the info on this 6 ARC..I have 2 other grendel's but this BHW barrel was on sale and wanted an 16" to test for my channel.. so when I watched all the videos on this ARC you could say I was a little upset.. that said, I'm waiting for Sanders Armory to get their barrels in stock and I'll be on the arc train and I'll be reloading for it.. hopping starline or any other good brass co will have cases available.. thanks John for putting out the real world numbers on this.. as many see it as a fad.
Not knocking your new 6mm I thinks it’s interesting... but your Grendel velocity seems a bit low as does your 308, almost sounds like the adds for the 350 legend the just as good as... or better than argument under skewed data commercials haha... also a neat round but please don’t pick the lows from the competition and the high from the round you are showcasing... I too have much “real world” chronograph data and while 6arc does have an advantage it is not near the advantage that your “real world” data shows. At least as compared to my chronograph data. Thank you for producing entertaining videos and supporting our great 2nd amendment!
I'm glad you did a video on the Arc vs the grindel.. I've been asking for one for a while everyone else has just been talkin about it not actually comparing ballistics at the range thanks
Earlier this year when I was just finishing my grendel build, all of a sudden 6mm arc started being advertised and popping up. Was a little salty about that, but the ammo situation for the arc calmed me. Plus I was building a creedmoor anyway.
I'd not be concerned. Grendel has been around a while, and ammo is available. 6mmARC, not so much. It's probably a great round, but I'd wait and see if it takes off.
Terminal ballistics winner is 6.5G. You mentioned terminal ballistics in your video @kotaboy32 tactical, but I think you were referring to exterior ballistics. True, exterior ballistics look good on 6A for hole punching. I'm sticking with grendel for the terminal ballistics winner.
It's a 108gr vs a 123gr both having the same muzzle energy and there's not a huge disparity in weight there so why would Grendel be the "terminal ballistics winner"?
Looks like a cool cartridge if I could get parts for it to try it. I'm just annoyed that now all the 6.5 Grendel parts (bolts, cases etc) are being taken up by the people frothing over 6mm ARC. I liked it better when people were freaking out over 6.5 CM and leaving us 6.5 Grendel guys alone. IMO if SIG's new case tech works out and becomes commercially available, the 6.5 Grendel would get even better (as would ALL calibers FWIW) and let me put a 123gr pill put of the barrel at 5.56 speeds. I love the Grendel. Ive taken an elk and several deer and it never let's me down hunting the mountains of Idaho.
@@blazerk9614 Who needs an AR ? In my reckoning the AR platform is flawed. I had rather have an AK or a PSL any day. The Weatherby will out preform any AR you can come up with. My Papa told me if it ant broke don't fix it . I have no need for a piece of junk AR. The damn things don't even make good clubs they break.
@@Caedin8 It's a pretty nasty FMJ though, just ask the hogs me and countless others have dropped QUICK with Wolf 6.5 Grendel 100gr FMJ. And I get a consistent 2MOA out of my 12" 1/8 5R Faxon barrel. Even better accuracy with Wolf if you go with 1/7.5 twist and regular rifling, and keep in mind that Bill Alexander worked with Wolf directly when designing the cartridge and chamber. It's meant to shoot steel-cased well. Here's a gel test of it: ruclips.net/video/b_WxJoCU7Ps/видео.html
John Capozzi thanks for sharing. Gel tests don’t always hold up in live performance. Glad it’s worked for you guys but I’d probably stick to a traditional expanding round. Take a look at this video to see an example of why I’d probably go with something else: ruclips.net/video/w1enrKm-T6A/видео.html
@@Caedin8 also the wolf Fmj was designed to tumble on impact like the 5.45. When hitting animals or humans it’s meant to yaw and let the tip lay over a bit. Still not an expanding round where hydrostatic shock would be as effective, but it should do more than punch a small hole.
A marginal impact at 300 yards is not going to be overcome by 1.62mm cross sectional width, and 60 additional grains of mass. In other words, choose the round that will give you adequate lethality, with less recoil, system weight, and greater accuracy.
Diff between a 6mm ARC and a .243 is the barrel twist. The standard 6mm ARC vs .243 standard at same barrel length. 6mm can handle the higher BC 108s better than the 1 in 9.5 twist .243 hence it catches and passes it in bullet drop and foot lbs out past 500 yds
In order to compare equal weight bullets you'd need a lighter bullet in Grendel which would have a lower BC and that's not going to help the comparison go more in favor of the Grendel not at all.
@@kotaboy32 Then show that, im interested in how two cases with similar gow could be so different unless you are just taking advantage of caliber jumps...and thats the flaw. No really, compare the ARC case with grendel case in the following calibers and let us know what you come up with 224Grendel vs 224ARC, 6mm grendel vs 6mmArc 6.5Grendel vs 6.5Arc and 30Grendel vs 30ARC.....which ever of these proves the most accurate is a winner.
@@gsxr1189 I enjoy the 107gr 264 out of the grendel or i just jump over to the 6mm grendel Sierra 264 Weight (grains) 107 Gr. Ballistic Coefficients and Velocity Ranges .445 @ a mere 2200 fps
A 108gr bullet in a 308 would be horrible in windy conditions. He compared popular effective bullets in each cartridge. Or you could say, Give me a bullet with 500+ BC for each cartridge. Guess what, 103-108gr for 6mm ARC, 123gr for 6.5 Grendel, and 168-175 gr for 308.
Fun discussion and a great opportunity to geek out! Realistically, vast majority of people leaving comments about 1000 yards have never even seen what a target looks like at that distance, let alone shoot at it. 6.5 Grendel is a fantastic round, specially for hunting. I'm going 6mm because I want to reach out to varmints with my 15 platforms, since I refuse to build myself an LR308. The 6mm bullets buck the wind better that other calibers, that's why I put a .243win up against any long range target round. Really looking forward to seeing what you build around that ARC.
Love the way you put this together Brother! I dig the new setup. I was waiting to see this kind of comparison. As you said I will not give up my Grendel, but it’s a good thing I have another precision set up lower to slap an ARC upper on. It’s awesome to have options this good that fit on AR15 platform. That has been my main thing. Besides I have extra bolts and mags so easy transition all I need is the barrel and a set of dies and I can get to work!!I am building an AR10 Creedmoore, there’s just something about a light weight precision/able to hunt with AR15!! Keep up the great work Brother!! Thanks for all your research to help us make some good decisions. I need an ARC in my inventory and I will have one! Semper Fi!
the 6mm arc just might be the best small frame AR round in existence. I've never been a fan of AR10s due to bulk and weight but the AR15 is great. For a SPR/DMR, the 6mm ARC seems about perfect given the limitations of the small frame platform. It also opens a ton of possibilities to the one lower, multiple upper guy that wants to do alot of things, including hunting.
Great video as always! Outstanding numbers for the 6mm Arc as compared to the 6.5 Grendel. The more I learn about the 6mm Arc, the more I'm thinking about building another upper. But haven't decided if I want a 16, 18, or 20 inch barrel. Cmmg has 16 and 20 inch barrel only for this caliber. After watching your range testing video I'm leaning more towards the 16 inch barrel. been looking for the brass also and reloading components. I think it's a very interesting round and has alot of potential!! Stay Safe and watch your Six my brother. Looking forward to your 6mmArc build!!
The more I watch what the 6mm ARC can do, the more I like it and want it. I'm glad I never had the money for an AR10 platform so I didn't spend my money on 308 and 6.5 Creedmoor rifles and ammo. I'll probably get them some time down the road, but that 6mm ARC is coming first.
Agree with everything you say. However an important point not discussed in your and most other similar videos is what the 6.5 Grendel was designed to do. Basically the 6.5 Grendel was not designed for target or hunting (where expanding rounds are permitted) shooting. It was specifically designed for the military in so far as it was designed to have the hitting power of an AK47 whilst keeping the accuracy of the 5.56 NATO round.
The Grendel fps seems low to me. I load the 123 gr at about 2450 fps out of my 20" barrel and according to my brass I could go higher. My 130 gr Bergers are about the same velocity and it is an amazing bullet in the Grendel. Wind drift is much better on Berger also. Let's face it neither the 6mm or the 6.5 the absolute maximum yards I would attempt on either would be 400 yards. Yes you might hit the deer but it very well may not kill humanely. Those are really the only numbers that mean anything. Any time a bullet gets below 2200 fps the wound cavity will shrink substantially, and make a hole the diameter of the bullet. Paper punching, well that's another story and there are better calibers that are better for long range shooting. The smaller the bullet diameter and weight the poorer long range potential IMO. Look at a 30 caliber 200 gr high bc bullet. The only other factor is speed. The faster you launch it the better it performs.
At 8:44 Why is the .308 projectile listed as 68 grains? I've NEVER seen a 308 bullet that light, and if I'm seeing that correctly, and it is put into the calculator at 68 grains, then that would drastically affect the end results
Rule of thumb for hunting . You want 800 - 1000 ft for deer.. You want 1000 -1250 For Hoggs.. You want 1300 and up for elk.. Moose 1800 and up.. Bullet selection is King when it comes to taking game. Me personally I only use Nosler Partition or Accubond. My personal Hunting rig is 18" Wilson Combat Tactical Hunter 308 Win with 1-8× Optic. I only use Nosler or Federal Premium 165g Partition. I've taken elk out to 300 yards and they dropped with 10 yards. Normal hunting distances are 350 yards and in for 90% of all hunting. Even though the 6 ARC can achieve those energy requirements for elk . I personally would NOT use it . Elk are very very tough . You want something heavy and hard rocking that elk . Obviously placement is key. I'm a firm believer in having 1 rifle for all your hunting needs. For me it's the 308 . It's perfect for deer , Hogs , and elk . It can be used for moose just keep it within 200 yards and use 180g Accubond or Partition ..
I like it. I'm a big Grendel fan. I think Hornady squeezed as much as could be squeezed out of the AR platform with the ARC. I won't be switching but I hope someone will start making some better mags for the Grendel/arc now. I'm a hunter and what the Grendel does is just perfect I'm not giving up my 15grains. One think the Grendel has over the ARC now is $6 box plinking ammo.
You hit the nail on the head with this take…. 2 years later and everything is the same. Grendel is probably a better mid range hunting round and cheaper but the arc has better ballistics
Awesome video! Very informative comparison. In fact I am putting together to build a 6mm ARC in 18 inch barrel and will follow with a 16 inch build soon. This video is vital to my decisions. I currently have 6.5 Grendel with 18 inch barrel and love it. I like that the 6mm ARC is a supercharged .243 making an Awesome hunting round.
So, the only thing I'm questioning is your Grendel velocity. I'm an avid reloader, so is a co-worker. He builds custom rifles, and has recently built a sub-moa Grendel. His muzzle velocity is 2620. My factory ammo is showing just above 2500. I'm wondering how you are really doing a legitimate comparison
Your chair looks comfortable. Yes, I'm jelly. Oh, nice ballistics info. You are on a higher plane of understanding than I am for sure. Thanks for sharing your experience and knowledge. Great vid Sir!
Main benefit of grendel, you can buy bulk wolf ammo 100 gn. Cheapest you can buy for the most part. Super low SD. Out of 18” still has 9mm energy at 1000 yards. 6mm ARC only makes sense in benchrest shooting. If you want self defense and long range. 6.5 Grendel. Not saying you can’t use arc for both but let me know where you can buy a 1000 rounds for under $300 for ARC.
I shoot a 6mm Hot which is the 6mm-6.5X47 Lapua with a no turn neck. It is even more accurate than the parent round. And the Lapua brass with small primer pocket is strong and quality is superb.
Magazine reliability ! If Magpul makes a reliable mag for this cartridge I can’t see how anyone would argue it’s not an upgrade for mk18/m4/mk12 platforms ..
let me know when magpul starts making mags out of stainless steal cause that's the only way you'll get that cartridge to fit right in the given space. SS is not near as thick as poly so your cases can be a bit wider and truly double stack.
@jon James they will build the polymer mag around the arc cartridge as they did with the 6.8 . If mags are a problem like with the Grendel it will hinder this rounds ability to take off . If they can make reliable magazines it will be a upgrade to 5.56 in every barrel length . Just saying facts .
@@foodforfighting4724 Why do people always think there are or were problems with Grendel mags. I've had 6.5 Grendel for about 8 years, and 6mm Predator for 3 years. Absolutely no problems with bolts or mags. I've shot my grendel with 5.56 mags and it'll work sometimes, but that's probably where the grendel mag problem rumors came from.
Question , So with the DMR acss HUD .308 scope . With the 6mm ARC ,Would you zero a half inch hight at 100 yards. Then drop an additional 1/4" ? I'm gonna try this see how close it is.
Well, it's a good thing I haven't started my 6.5 build yet. Although I'd like to see what the 6mm would do out of 12in and 20in barrels. Then I'd buy the round with the best all around performance. 6.5 is getting adorable now though (when ammo isn't all bought up).
Thank you! Thank you! I was hoping that this 6mm arc was not just a fluke. From what I read it just looked promising. Your earlier video there was a look in your eyes and a spark in your voice about this round. If you don't mind my plans is to follow you thru your build and try to build my first precision rifle. The best, John Huskey
I would like to see you hand load 6.5 Grendel and 6 mm Arc with same weight bullets and see what you get. I'm sure you can get a 108 or 110 grain weight in 6.5 Grendel.
I don't have a 6mm ARC, yet, but I have a 20" Grendel and I tested the 6.5 100grain ELD against the Hornady ARC published data for a 100gn 6mm bullet with 2 separate powders and in all cases the Grendel velocity beat the hornady listed data for the ARC. See my video. ruclips.net/video/0bsQxgeUCyo/видео.html
Only issue is the BC for the AEC round will be better than that of the Grendel for the same bullet weight. I would be more concerned about which round would have the better hunting bullets. Grendel has a reputation for not opening /mushrooming properly on game animals. The AEC might have better hunting bullets available and increased bullet speed would help it open properly.
6mmARC looks sweet I just built a 6.5 grendel haha I'm no long range shooter. But as for hunting elk with the ARC. I personally dont think I'd do it. But I dont know much about it. Sectional density, bullet expansion and penetration are what needs to be looked at for hunting something like elk. I've seen elk taken at 400 yards with the grendel. With 130 grain bullets. Personally (which is really what it comes down to) as much as I love my grendel. I'll take my 270 9 times out of 10 for something as big as elk. And I probably wouldn't shoot more than 200 yards if I did take my grendel for elk.
Shooter's Calculator rocks. I saw that they're working on some changes in the background. Can't wait to see what they end up with. Great video, Kotaboy!
For long range 6.5 Grendel needs more velocity meens longer barrel. It is why a lot of grendel rig use 22-24" barrel (and sometimes 20"). 18" in grendel is relativity short for long range.
I don't use ARs, only bolt guns & single shots. For PA hunting deer/hogs/coyote inside 200 yards, what does the 6mm ARC offer over my 6mm BR Norma or 6.5 Grendel bolt guns? If anything I plan to rebarrel a .223 to 6x45mm.
in the 6.5 grendel you need to do it a better justice. go to its heaviest rated bullet.... 130gr. obviously there are heavier bullets out there. Not saying that its better at long range but will get closer than the 123. On a side note..... 6mm holds the world record for the most accurate bullet. Dont forget 7mm(6.8)spc. And to make it even more interesting MATCH the BCs.
This caliber is pointless if you are already into another caliber like 6.5 grendel or 6.8. It's nice in theory but not practical to get a new setup if you are already invested in one of those calibers. Also 6.5 has the added benefit of cheap steel cased for plinking.
These are effective less than 350 yard for small game. Beyond 500 yards you need bolt rifle or longer barrel. And who hunts at that distance? Grendel ammo is more affordable.
The 6ARC is prob the option if your choosing a competition round. If on the other hand your wanting an AR 15 cartridge that hits a ton harder than the 223/5.56, is available in affordable steel case to use for predators/whitetail deer/self defense... GRENDEL ALL DAY LONG IF you're competing in an "Unknown Sniper" comp...might want to choose the 6ARC
The Grendel does everything I want it to do and ammo is available. I also have 5.56 rifles and a 6.5 Creedmoor so my full range of capabilities is covered. Just my opinion but I don’t see a need for still another caliber.
In Missouri, the 6mm ARC ammo is more plentiful than 6.5 Grendel. In fact, I haven't seen ANY Grendel ammo in many months. However, the 6mm ARC seems to have ammo on the shelf most of the time at a variety of retailers.
Have you done any hunting with the cartridge? Looking for video but there isn’t much info out there yet. From what few videos I’ve seen it is performing very well with the bullets out on pigs and deer.
I have the 308,6.5 they are great calibers,they shot heavier bullet for big game that's all great stuff,but do they fit in a AR platform ? The 6arc does fit in a AR platform, and does it very good it's legal to hunt deer with,it has little recoil being able to stay on target,something you can't do with larger calibers,to me the 6arc made the AR platform perfect,the way it was designed for,make no mistake,after 600 yards it catches the 308 in performance,and step out with the 6.5 at long range,did I mention how little the recoil is?My long range follow up shots are fast,it's shoots harder,and further then the .223.I now would like one in a pistol platform I think it would be better then a full size barrel in the .223,but lighter,and more concealable.I would suggest that everyone have one,it would also make a good counter sniper setup,I think taking all aspects of shooting into consideration,it's a winner that's for sure.
Go to the Shooters Calculator Pick kinetic Energy and joules go look up the good stuff 6.5 Grendel In Underwood ammo or Hornady 123 gr SST and 6.5 Grendel Spanks the 6mm everywhere I searched for good ammo
I love my grendels all 3 of them. 12” 16” and 18” but that 16” barrel is about to get pulled for a 16” or 18” faxon 6mm arc barrel. I was wondering what if you put the 107gn Sierra match king in the Grendel how it would stack up against that 108gn eld. Although they don’t make factory 107gn Grendel loads. But I’ll still be bringing out the Grendel for the deer. I won’t be shooting deer any farther than 300yds and I know for a fact that 120gn federal fusion will drop a 160lb white tail in its tracks from 220yds. And ima actually be trying out the new Barnes 115gn vor-tx this year too. And as far as the acss reticle I’ve got the 3-18x hud dmr on my 18” faxon Grendel and it lines up almost perfect out to 500yds with a 3/4” high zero at 100yds and the 4-14x Orion on my 16” Grendel works out to 600yds with the same zero. I’ve got the 1-8x on my 12” Grendel but haven’t tried it any farther than 200yds yet but I’m sure I can play around with the zero and get it close. Btw my 3-18x has the 223/5.56 reticle.
I've got 3 different 6mm ARC's that I'm building but still waiting for the Hornady Precision Hunter to come out. Now I have a 12.5" 6.5 Grendel I built on a ZEV upper and lower receivers and a ballistic advantage barrel. I've taken prong horn, deer, and elk within 200 yds. So my 6mm ARC has a lot to of catching up to do.
I can find .308 everywhere and within 400 yards, it is KING. 800 and 1,000 yard shooting will never happen on the east cost in the woods. .308 Wolf military surplus is available for plinking too .
What do you think about the 6mm ARC handloaded with a 70 grain bullet for coyotes? Do would expected speeds be according to your research and do you think it would have problems feeding?

The margin of error is so close that a long range most hunters can’t accurately call wind to make a difference I own both 6.5 Grendel and 6mm arc and love them equally they the most efficient cartridges on a ar15 platform so much that my BCM and Daniel Defense 556’s are relegated to home defense and steel plinking
You have convinced me about the 6mm ARC, however my 20 inch Grendel build has a muzzle velocity of 2580fps, which does add to its range. I might eventually get an ARC after some other projects and saving up some funds. On another subject.....have you done anything more with the 458 socom? I plugged in some numbers and found out that the 1-6 Raptor can be used with it out to 300 yards, the 18 inch ranging bars are 9inches for bracketing, and the wind holds are closer to 4 &8 mph.
excellent comparison. I suspect this a distinction that the deer I shoot wont be able to tell. The only caveat for hunters is to remember that rifles are not yet energy weapons; and "foot pounds of energy" while useful, do not directly corelate with ethical killing ability .
Yes! Loving to be able to see that data while hearing it. That's helps a great deal. Thank you! I'm still not seeing a reason to get away from .308 for a default multipurpose rifle. Fighting ranges, hunting ranges, ammo prices, ammo stores and availability, et cetera, et cetera. For sniper work? Hmmm. Maybe 6.5CM. For your standard dude who may only own one or 2 rifles, I'm still liking 5.56 and .308; and for only one had gun, and only 1 rifle period, .308 BT Spitzer is still in the lead for me.
6mm Arc is very interesting ammo does need to catch up before I pull the trigger on it. Pretty much every caliber out there now. Let’s talk KPS and Sectional density. I know not everyone has powerful rifles for just hunting but my thought is it has to be able to drop what I am shooting at quickly and effectively. I say that but .243 does drop medium game animals.
Sir, I believe this is a viable option in the AR platform. I have looked at the data and believe in the reasoning for this. Some will look at this strictly as a 'wildcat'. However, as for Department of Defense and military, it will be as to what remains/becomes the standardized cartridge. For the average rifleman it is still 5.56mm.When the 6.8mm came out DOD did not adopt that (as a whole) for their cartridge. The popularity of this cartridge will be left to what ammunition logisticians influence decision makers to stockpile for the next 50 years or so. Nice video.
I agree with the majority of this entire review. All things being equal, real world velocities, and impact energies as they are, being within 100ft/lb at 300 yards, the 6.5 grendel will wound better than the 6mm arc. A 6.5 grendel has been proven effective on elk at those ranges. It is not my go to and I'm not arguing it as a suitable elk round but it has been used effectively as one. The additional frontal area of the 6.5 and added momentum from the heavier round tends to lend to better penetration in addition to slightly lower impact speeds tend to allow the rounds to hold together better under impact. I believe those taking elk typically aren't using 18" barrels, but it would not shock me either. A .243 is considered marginal on elk and in many places is THE MINIMUM legal round. A 6mm arc is quite a bit less powerful on paper than a .243 however it does far better in shorter barrels. That said, the 6.5 grendel is considerably more potent as barrel lengths reach the 20-24" range pushing the same loads at 100-200 fps faster than the 18". And given equal impact energy, it SHOULD be a more potent round on game due to the extra diameter. All that said above, inside say 350-400 yards with 20-24" barrels and inside 300-350 yards with 16-18" barrels, both rounds are fantastic on deer size game. And you'd likely not see any difference in on game performance. As game gets larger, the bullet diameter differences, especially if more durable projectiles are used, will lend itself in favor of the 6.5 grendel pretty soundly. Both rounds allow for far more effective practice and better shot placement due to that to the average shooter so they both in a way punch well above their "weight class" and that's very good for both Hunter and quarry. All in all, very good content. Well done and thorough. Thanks!
@@kcb3887 Unfortunately that isn't the case with the Hornady Black 123 ELD's I shot in this video. I got 2370, it was accurate but not much punch. ruclips.net/video/EvpKc3dq0nY/видео.html
@@ErikS308 One of the things I have to do when testing is shoot factory ammo. In my last test, I got an average of 2370 which in my mind is slow, it's accurate but slow.

Not sure if you saw the range review I did on the PSA 18 inch 6.5 Grendel but here's the link: ruclips.net/video/EvpKc3dq0nY/видео.html
6mm arc sounds very interesting but so did the valkirey. I think I'll stick with the grendel for now and wait and see on the 6mm
Valkyrie hasn’t failed. Mine sure hasn’t. Shooting 80 gr Sierra Mk and cfe223 I get sub moa at 300 yards easy. Valkyrie is a reloaders dream. But I’m with most others...I’ll stay with my Grendel.
What didn’t it deliver?? I have folks shooting their 85 and 90 bullets sub moa out of The Valkyrie out to 1000 plus yards!! How’s that a fail? That’s what it is supposed to be doing. It takes work to get it there, but that’s the beauty of things. Anything worth having you have to work for. But hey your opinion is yours. I beg to differ and that’s my right. Out.
The more you look into the arc the more impressed you’ll be. But it really depends on the application.
@Nick Rodriguez sounds like you're quite butt hurt. The valkyrie is a target and varmint round only
@Nick Rodriguez the Valkyrie performs better than any AR15 round at distance. As for AR10 which is a totally different platform (whole new gun) it performs better than 308 in everything but energy on target and comes close to 6.5 CM on everything but energy. If you want a lighter weight long range AR15 that can hit at incredible range Valkyrie does it.
Looks like things have gone full circle and we're back at .243. . . LMAO
LOL, I was just telling someone about a police/military sniper manual published in 1993 was giving .243 a 600 yard max range.
@@aspenair8988 That might have been true aerodynamical technology in bullets has come leaps and bounds in the past 10yrs. In 1993 243cal bullets sucked.
Aspen Air Could’ve been a “practical” max range, taking into account that police snipers don’t have much business shooting that far anyway.
@Nick Rodriguez yes but with 58gr vmax at just under 4000 fps it will penetrate most body armor produced

I've been really interested in this exact comparison. This idea of squeezing basicly a .243 into an AR-15 platform could be a game changer. Thank you for the info.
Look at the 6mmAR. Don’t support crooks.
7mm Raptor
@@maxwelsnyder3672 what do you mean? And who makes the 6mm AR?
.243 ar10s are decently common.
@@BushmasterRaZ they are...but .243 performance in an AR-15 platform as opposed to an AR-10 is very appealing.
The 6 looks good, but still uses the Grendel case. With people still having pressure issues breaking bolts, is this going to now transfer to the ARC? I’m pretty well invested in the 6.8 as it is, and the problem I see with all of these -15 cartridges is they are unable to get the kinetic energy to justify their use at ranges past 4-600yds for anything other than pinching paper. It just seems to be the limitation of the casing. I wish the development of the arc utilized a casing a little more forgiving in an AR-15 platform. I’ll keep up to date with the progress, but will likely stick with the 6.8 that is highly effective at practical ranges for the platform and utilizing a case less prone to parts breakages. Thanks for the vid
the grendel bolts issue was on people's lips 10 years ago. Now a days people make bolts even thinner than for the Grendel, like the POF revolution: a 308 bolt for an AR15 sized carrier (some bolt diameter as .223 but with a .308 case head cut out, very thin side walls).
The Grendel bolt issue wasn't a problem with the grendel. It was a metallurgy issue.
My Grendel bolt extractor broke in 400 rounds but it was a BCA bolt.
The type two bolt I am using in one of my 6.5 Grendel AR;s has 2k rounds without a problem and my loads are only a grain or two from max. That problem was cured by Alexander Arms a few years ago. Load correctly, set up your chamber, barrel torque and head spacing , and you should have no problems.
It's all about trying to get people to buy the "newest great thing".
The advantage for 6.5 grendel to me is rifle weight. The .308 iis a much heavier platform. The 6.5 allows a slightly bigger bullet in the 123 over the arcs 108 . The differencs isnt much but still for my hunting needs the grendel seems to work . For punching holes in paper the arc might be the better choice.
6.5 Grendel was a goal to own, when the cost comes down I’ll consider it, thanks for the time and info
that's respectable... picked up my barrel at my local manufacturer for $100 and a upper-lower combo for the same price and that's what started it for me. I've started buying wolf 6.5 Grendel at 50c a shot so we'll see how it works out!
I just bought a box of 500 6.5 Grendel from Wolf because it's becoming rare. I don't even have the rifle built yet, but I wanted some inexpensive ammo for zeroing and plinking. I'd hop on inexpensive ammo if you can afford it.
For me, I went with the 6.5 Grendel because it is more available and I am not shooting past 500 yards because this will be a deer hunting rig. No reason to pay twice as much for 6mm ARC ammo, barrels and parts.
I built my own AR-15 chambered in the 6mm ARC and have less than $500 in it right now. first group with Hornady black was .75 inches. 24" stainless barrel so I can get most all the velocity that the cartridge offers in a bolt gun.
I Have 3 ARC’s However My 6.5 PRC Holds & Delivers Over A 600 BC Which Is The Most Important In Ballistic Co-Efficiency. Great Footage. Keep It Coming. Both Are Good For Over 1200 Yards With Excellent Optics. Especially The 6.5 PRC’s.
Hornady plays games using different barrel lengths and bullets then comparing. The 22arc is a prime example. When you look at the reloading data, the 224 valk. Is equal/better than 22 arc. The 6.8spc is tested with a 16" barrel while most other rounds are tested with a 24" barrel. 8 inches of barrel (200 fps) makes a difference.
I shoot both the 6.5 Grendel and the 6MM ARC. Both of them are awesome rounds. I chambered the 6.5 Grendel in an 18 inch barrel and the 6 MM ARC out of a 20’ inch barrel. Using them both for different purposes. 6.5 Grendel for camping and the 6 ARC for competition shooting. These rounds were very hard to find during the Plandemic and I ended up finding a plug at the gunshows and he would sell both ballistics in bulk. It was expensive but worth it at the time. Now I can find 6MM ARC easily but the Grendel is still pretty illusive as it isn’t found in as many places as the 6 MM ARC.
Honestly the Grendell was originally conceived for Army special forces to be able to target longer distance targets with the shorter rifle chanbered in 14" most of the time and have more penetrating power even than the .223 round they carry now.
6mm is awesome however.
RUclips must be smokin' some crack with their advertising decisions.

Gotta stay with my 6.5 Grendal bolt gun and AR pistol 12" build under way now
F.Y.I. I'm getting 2250 fps out of 123's with my 12" 6.5 Grendel reloading using Benchmark powder. Can't jive with him saying he only getting another 100 fps with another 8" of Barrel length Specially with my buddy getting 2500 fps in his 18" . Don't know why these guys gotta fudge the #'s
You're gonna love that pistol chambered in Grendel. I finished an Alexander Arms 11.5" pistol build earlier this year. Slapped a Razor gen 3 1-10 on it and its the closest I've come to a true do it all build. It is the absolute pride and joy of my collection. From cqb all the way out to 1000, it gets the job done.
Something looks off. A 123gr 6.5 Grendel projectile out of an 18 inch barrel should still be supersonic past 1,000 yards. And a 168gr projectile in a 308Win is NOT supersonic at 1,000 yards. A 175gr will be, but not the 168.
Good info. I paid $21.99 a box locally for 6mm ARC. I can't wait until Criterion releases their barrels so I can complete my build.
Honestly logistics was the major factor in steering me toward 6 ARC. Uses small primers, powders I already keep on hand for 223, selection of bullets out the wa-zoo. Everything needed to make a quality bullet is a lot easier and cheaper to get when you can find it. Couple that with a excellent range the bullet stays supersonic at and it was a no brainer.
I bought all the upper parts for a 264LBC (6.5 grendel) the day before Hornady released all the info on this 6 ARC..I have 2 other grendel's but this BHW barrel was on sale and wanted an 16" to test for my channel.. so when I watched all the videos on this ARC you could say I was a little upset.. that said, I'm waiting for Sanders Armory to get their barrels in stock and I'll be on the arc train and I'll be reloading for it.. hopping starline or any other good brass co will have cases available.. thanks John for putting out the real world numbers on this.. as many see it as a fad.
Not knocking your new 6mm I thinks it’s interesting... but your Grendel velocity seems a bit low as does your 308, almost sounds like the adds for the 350 legend the just as good as... or better than argument under skewed data commercials haha... also a neat round but please don’t pick the lows from the competition and the high from the round you are showcasing... I too have much “real world” chronograph data and while 6arc does have an advantage it is not near the advantage that your “real world” data shows. At least as compared to my chronograph data. Thank you for producing entertaining videos and supporting our great 2nd amendment!
I'm glad you did a video on the Arc vs the grindel.. I've been asking for one for a while everyone else has just been talkin about it not actually comparing ballistics at the range thanks
Earlier this year when I was just finishing my grendel build, all of a sudden 6mm arc started being advertised and popping up. Was a little salty about that, but the ammo situation for the arc calmed me. Plus I was building a creedmoor anyway.

@@ninjascout468 short barrel grendels are awesome
I'd not be concerned. Grendel has been around a while, and ammo is available. 6mmARC, not so much. It's probably a great round, but I'd wait and see if it takes off.
Any thoughts on hunting with a 13inch barrelled upper?
Terminal ballistics winner is 6.5G. You mentioned terminal ballistics in your video @kotaboy32 tactical, but I think you were referring to exterior ballistics. True, exterior ballistics look good on 6A for hole punching. I'm sticking with grendel for the terminal ballistics winner.
It's a 108gr vs a 123gr both having the same muzzle energy and there's not a huge disparity in weight there so why would Grendel be the "terminal ballistics winner"?
Looks like a cool cartridge if I could get parts for it to try it. I'm just annoyed that now all the 6.5 Grendel parts (bolts, cases etc) are being taken up by the people frothing over 6mm ARC. I liked it better when people were freaking out over 6.5 CM and leaving us 6.5 Grendel guys alone. IMO if SIG's new case tech works out and becomes commercially available, the 6.5 Grendel would get even better (as would ALL calibers FWIW) and let me put a 123gr pill put of the barrel at 5.56 speeds. I love the Grendel. Ive taken an elk and several deer and it never let's me down hunting the mountains of Idaho.
You can keep it . The .257 Weatherby Magnum can do anything the 6 mm Arc can do and I already have the Weatherby.
Not out of an AR

Who needs an AR ? In my reckoning the AR platform is flawed. I had rather have an AK or a PSL any day. The Weatherby will out preform any AR you can come up with.

@@Caedin8 It's a pretty nasty FMJ though, just ask the hogs me and countless others have dropped QUICK with Wolf 6.5 Grendel 100gr FMJ. And I get a consistent 2MOA out of my 12" 1/8 5R Faxon barrel. Even better accuracy with Wolf if you go with 1/7.5 twist and regular rifling, and keep in mind that Bill Alexander worked with Wolf directly when designing the cartridge and chamber. It's meant to shoot steel-cased well.
Here's a gel test of it:
ruclips.net/video/b_WxJoCU7Ps/видео.html
John Capozzi thanks for sharing. Gel tests don’t always hold up in live performance. Glad it’s worked for you guys but I’d probably stick to a traditional expanding round.
Take a look at this video to see an example of why I’d probably go with something else: ruclips.net/video/w1enrKm-T6A/видео.html
@@Caedin8 also the wolf Fmj was designed to tumble on impact like the 5.45. When hitting animals or humans it’s meant to yaw and let the tip lay over a bit. Still not an expanding round where hydrostatic shock would be as effective, but it should do more than punch a small hole.
I'm with 308 WIN. Because 300 yards. DRT.
A marginal impact at 300 yards is not going to be overcome by 1.62mm cross sectional width, and 60 additional grains of mass. In other words, choose the round that will give you adequate lethality, with less recoil, system weight, and greater accuracy.
Diff between a 6mm ARC and a .243 is the barrel twist. The standard 6mm ARC vs .243 standard at same barrel length. 6mm can handle the higher BC 108s better than the 1 in 9.5 twist .243 hence it catches and passes it in bullet drop and foot lbs out past 500 yds
What about dropping down to 110 grain 6.5 grendel or a 100 is the bc s not as good as 123 gr ?
Oh u need to compare same grain bullets or close , makes a big difference
we compared the ELD, if you went closer to the grain, the comparison would be even further in favor of the ARC
In order to compare equal weight bullets you'd need a lighter bullet in Grendel which would have a lower BC and that's not going to help the comparison go more in favor of the Grendel not at all.
@@kotaboy32 Then show that, im interested in how two cases with similar gow could be so different unless you are just taking advantage of caliber jumps...and thats the flaw.

Fun discussion and a great opportunity to geek out! Realistically, vast majority of people leaving comments about 1000 yards have never even seen what a target looks like at that distance, let alone shoot at it. 6.5 Grendel is a fantastic round, specially for hunting. I'm going 6mm because I want to reach out to varmints with my 15 platforms, since I refuse to build myself an LR308. The 6mm bullets buck the wind better that other calibers, that's why I put a .243win up against any long range target round. Really looking forward to seeing what you build around that ARC.

Keep up the great work Brother!! Thanks for all your research to help us make some good decisions. I need an ARC in my inventory and I will have one!
Semper Fi!
SFMF !
the 6mm arc just might be the best small frame AR round in existence. I've never been a fan of AR10s due to bulk and weight but the AR15 is great. For a SPR/DMR, the 6mm ARC seems about perfect given the limitations of the small frame platform. It also opens a ton of possibilities to the one lower, multiple upper guy that wants to do alot of things, including hunting.
Great video as always! Outstanding numbers for the 6mm Arc as compared to the 6.5 Grendel. The more I learn about the 6mm Arc, the more I'm thinking about building another upper. But haven't decided if I want a 16, 18, or 20 inch barrel. Cmmg has 16 and 20 inch barrel only for this caliber. After watching your range testing video I'm leaning more towards the 16 inch barrel. been looking for the brass also and reloading components. I think it's a very interesting round and has alot of potential!! Stay Safe and watch your Six my brother. Looking forward to your 6mmArc build!!
Reb, given the choice, I would personally go with the 20 inch barrel. You'll pick up a couple fps out of it.
I bought a 6mm Predator a few years ago. 22 inch barrel. I have no problem hitting 2700-2750 fps with a 103eldx.
The more I watch what the 6mm ARC can do, the more I like it and want it. I'm glad I never had the money for an AR10 platform so I didn't spend my money on 308 and 6.5 Creedmoor rifles and ammo. I'll probably get them some time down the road, but that 6mm ARC is coming first.
Agree with everything you say. However an important point not discussed in your and most other similar videos is what the 6.5 Grendel was designed to do. Basically the 6.5 Grendel was not designed for target or hunting (where expanding rounds are permitted) shooting. It was specifically designed for the military in so far as it was designed to have the hitting power of an AK47 whilst keeping the accuracy of the 5.56 NATO round.
I'm burned out from all the new greatest new cartridges. It's all been done before.
The Grendel fps seems low to me. I load the 123 gr at about 2450 fps out of my 20" barrel and according to my brass I could go higher. My 130 gr Bergers are about the same velocity and it is an amazing bullet in the Grendel. Wind drift is much better on Berger also. Let's face it neither the 6mm or the 6.5 the absolute maximum yards I would attempt on either would be 400 yards. Yes you might hit the deer but it very well may not kill humanely. Those are really the only numbers that mean anything. Any time a bullet gets below 2200 fps the wound cavity will shrink substantially, and make a hole the diameter of the bullet. Paper punching, well that's another story and there are better calibers that are better for long range shooting. The smaller the bullet diameter and weight the poorer long range potential IMO. Look at a 30 caliber 200 gr high bc bullet. The only other factor is speed. The faster you launch it the better it performs.
At 8:44 Why is the .308 projectile listed as 68 grains? I've NEVER seen a 308 bullet that light, and if I'm seeing that correctly, and it is put into the calculator at 68 grains, then that would drastically affect the end results
That's a typo in the title, it did not go into the calculations, if it did the fps would be 34k fps......lol good catch though
Love is recent context from you ! Really enjoying it!
Rule of thumb for hunting .
You want 800 - 1000 ft for deer..
You want 1000 -1250 For Hoggs..
You want 1300 and up for elk..
Moose 1800 and up..
Bullet selection is King when it comes to taking game. Me personally I only use Nosler Partition or Accubond. My personal Hunting rig is 18" Wilson Combat Tactical Hunter 308 Win with 1-8× Optic. I only use Nosler or Federal Premium 165g Partition. I've taken elk out to 300 yards and they dropped with 10 yards.
Normal hunting distances are 350 yards and in for 90% of all hunting.
Even though the 6 ARC can achieve those energy requirements for elk . I personally would NOT use it . Elk are very very tough . You want something heavy and hard rocking that elk . Obviously placement is key.
I'm a firm believer in having 1 rifle for all your hunting needs. For me it's the 308 . It's perfect for deer , Hogs , and elk . It can be used for moose just keep it within 200 yards and use 180g Accubond or Partition ..
Great info, thank you
I agree completely. If it ant broke don't fix it.
I'll take good old Remington core Lokt any day.
Great point too.

Really. I don't like Remington ammunition. It gets recall a lot.

I like it. I'm a big Grendel fan. I think Hornady squeezed as much as could be squeezed out of the AR platform with the ARC. I won't be switching but I hope someone will start making some better mags for the Grendel/arc now. I'm a hunter and what the Grendel does is just perfect I'm not giving up my 15grains. One think the Grendel has over the ARC now is $6 box plinking ammo.
You hit the nail on the head with this take…. 2 years later and everything is the same. Grendel is probably a better mid range hunting round and cheaper but the arc has better ballistics
@@dionysis84 and better ballistics don't make better terminal performance all the time. Which if your paper punching does not matter.
Awesome video! Very informative comparison. In fact I am putting together to build a 6mm ARC in 18 inch barrel and will follow with a 16 inch build soon. This video is vital to my decisions. I currently have 6.5 Grendel with 18 inch barrel and love it. I like that the 6mm ARC is a supercharged .243 making an Awesome hunting round.
It’s my understanding that 6ARC is .243 lite
So, the only thing I'm questioning is your Grendel velocity. I'm an avid reloader, so is a co-worker. He builds custom rifles, and has recently built a sub-moa Grendel. His muzzle velocity is 2620. My factory ammo is showing just above 2500. I'm wondering how you are really doing a legitimate comparison
My exact thought. The 6 ark I thought was replacing the 556 in m16. I’m getting 2550.
In 10 years if the arc is still a thing I might make the switch.
Your chair looks comfortable. Yes, I'm jelly. Oh, nice ballistics info. You are on a higher plane of understanding than I am for sure. Thanks for sharing your experience and knowledge. Great vid Sir!
BOOOOOOOOMMMMMM!!!!!
Main benefit of grendel, you can buy bulk wolf ammo 100 gn. Cheapest you can buy for the most part. Super low SD. Out of 18” still has 9mm energy at 1000 yards. 6mm ARC only makes sense in benchrest shooting. If you want self defense and long range. 6.5 Grendel. Not saying you can’t use arc for both but let me know where you can buy a 1000 rounds for under $300 for ARC.
I shoot a 6mm Hot which is the 6mm-6.5X47 Lapua with a no turn neck.
It is even more accurate than the parent round. And the Lapua brass with small primer pocket is strong and quality is superb.
Thank you very much for making this video very informative my question is why can’t they call it 6 Grendel if we have the 6 Creedmoor?
Licensing alone I suspect. 300AAC, 300BO, 300 Whisper. Familiar with the licensing history of the Grendel? It is a dramatic story.
Magazine reliability ! If Magpul makes a reliable mag for this cartridge I can’t see how anyone would argue it’s not an upgrade for mk18/m4/mk12 platforms ..
let me know when magpul starts making mags out of stainless steal cause that's the only way you'll get that cartridge to fit right in the given space. SS is not near as thick as poly so your cases can be a bit wider and truly double stack.
@jon James they will build the polymer mag around the arc cartridge as they did with the 6.8 . If mags are a problem like with the Grendel it will hinder this rounds ability to take off . If they can make reliable magazines it will be a upgrade to 5.56 in every barrel length . Just saying facts .
@@foodforfighting4724 6.8 cases arent as big in diameter as 6.5G...
@@foodforfighting4724 Why do people always think there are or were problems with Grendel mags. I've had 6.5 Grendel for about 8 years, and 6mm Predator for 3 years. Absolutely no problems with bolts or mags. I've shot my grendel with 5.56 mags and it'll work sometimes, but that's probably where the grendel mag problem rumors came from.
Why use magpul mags? What's wrong with metal mags? They work for the military.
Question , So with the DMR acss HUD .308 scope . With the 6mm ARC ,Would you zero a half inch hight at 100 yards. Then drop an additional 1/4" ? I'm gonna try this see how close it is.
Well, it's a good thing I haven't started my 6.5 build yet. Although I'd like to see what the 6mm would do out of 12in and 20in barrels. Then I'd buy the round with the best all around performance. 6.5 is getting adorable now though (when ammo isn't all bought up).
Thank you! Thank you! I was hoping that this 6mm arc was not just a fluke. From what I read it just looked promising. Your earlier video there was a look in your eyes and a spark in your voice about this round. If you don't mind my plans is to follow you thru your build and try to build my first precision rifle.
The best,
John Huskey
I would like to see you hand load 6.5 Grendel and 6 mm Arc with same weight bullets and see what you get. I'm sure you can get a 108 or 110 grain weight in 6.5 Grendel.
I don't have a 6mm ARC, yet, but I have a 20" Grendel and I tested the 6.5 100grain ELD against the Hornady ARC published data for a 100gn 6mm bullet with 2 separate powders and in all cases the Grendel velocity beat the hornady listed data for the ARC. See my video. ruclips.net/video/0bsQxgeUCyo/видео.html
Only issue is the BC for the AEC round will be better than that of the Grendel for the same bullet weight. I would be more concerned about which round would have the better hunting bullets. Grendel has a reputation for not opening /mushrooming properly on game animals. The AEC might have better hunting bullets available and increased bullet speed would help it open properly.
I'm a grendel fanboy I'll say it and its gonna take more than a arc to sway me
I still like my 6.5 Grendel , works great for my style of shooting 👍🏻
6mmARC looks sweet I just built a 6.5 grendel haha I'm no long range shooter. But as for hunting elk with the ARC. I personally dont think I'd do it. But I dont know much about it. Sectional density, bullet expansion and penetration are what needs to be looked at for hunting something like elk. I've seen elk taken at 400 yards with the grendel. With 130 grain bullets. Personally (which is really what it comes down to) as much as I love my grendel. I'll take my 270 9 times out of 10 for something as big as elk. And I probably wouldn't shoot more than 200 yards if I did take my grendel for elk.
Great vid bro as usual
I'm waiting on Peterson to start making brass.
What Bolt and Mags are you planning to run?
Thanks
You can get the 6.5G in a lighter bullet than 123gr I wonder how the ballistic would compare if it was 100gr 6.5G to the 108gr 6mm?
Shooter's Calculator rocks. I saw that they're working on some changes in the background. Can't wait to see what they end up with. Great video, Kotaboy!
Maybe they will compare closer bullet weights. I push a 107gr seirra that surpasses the arc... all day long.
Can you try the same test using PPU 110 grain 6.5 Grendel ?
For long range 6.5 Grendel needs more velocity meens longer barrel. It is why a lot of grendel rig use 22-24" barrel (and sometimes 20"). 18" in grendel is relativity short for long range.
I don't use ARs, only bolt guns & single shots. For PA hunting deer/hogs/coyote inside 200 yards, what does the 6mm ARC offer over my 6mm BR Norma or 6.5 Grendel bolt guns? If anything I plan to rebarrel a .223 to 6x45mm.
in the 6.5 grendel you need to do it a better justice. go to its heaviest rated bullet.... 130gr. obviously there are heavier bullets out there. Not saying that its better at long range but will get closer than the 123.
On a side note..... 6mm holds the world record for the most accurate bullet. Dont forget 7mm(6.8)spc. And to make it even more interesting MATCH the BCs.
As for as the sound barrier watch Mark and Sam. They shoot through sound barrier all the time and bullets are still stable.
This caliber is pointless if you are already into another caliber like 6.5 grendel or 6.8. It's nice in theory but not practical to get a new setup if you are already invested in one of those calibers. Also 6.5 has the added benefit of cheap steel cased for plinking.
Dang And I just finished building a Grendel upper this last Christmas
These are effective less than 350 yard for small game. Beyond 500 yards you need bolt rifle or longer barrel. And who hunts at that distance? Grendel ammo is more affordable.
6mm ARC reminds me of the 6mm Optimum concept. Therefore I am very interested in it and hope the market backs it up.
The 6ARC is prob the option if your choosing a competition round. If on the other hand your wanting an AR 15 cartridge that hits a ton harder than the 223/5.56, is available in affordable steel case to use for predators/whitetail deer/self defense... GRENDEL ALL DAY LONG
IF you're competing in an "Unknown Sniper" comp...might want to choose the 6ARC
Great job, love all that you show us!
The Grendel does everything I want it to do and ammo is available. I also have 5.56 rifles and a 6.5 Creedmoor so my full range of capabilities is covered. Just my opinion but I don’t see a need for still another caliber.
In Missouri, the 6mm ARC ammo is more plentiful than 6.5 Grendel. In fact, I haven't seen ANY Grendel ammo in many months.
However, the 6mm ARC seems to have ammo on the shelf most of the time at a variety of retailers.
Need more manufacturers to put out more ARC ammo especially 90 grain. I believe that is gonna be the sweet spot for 6 ARC.
Have you done any hunting with the cartridge? Looking for video but there isn’t much info out there yet. From what few videos I’ve seen it is performing very well with the bullets out on pigs and deer.
I have the 308,6.5 they are great calibers,they shot heavier bullet for big game that's all great stuff,but do they fit in a AR platform ? The 6arc does fit in a AR platform, and does it very good it's legal to hunt deer with,it has little recoil being able to stay on target,something you can't do with larger calibers,to me the 6arc made the AR platform perfect,the way it was designed for,make no mistake,after 600 yards it catches the 308 in performance,and step out with the 6.5 at long range,did I mention how little the recoil is?My long range follow up shots are fast,it's shoots harder,and further then the .223.I now would like one in a pistol platform I think it would be better then a full size barrel in the .223,but lighter,and more concealable.I would suggest that everyone have one,it would also make a good counter sniper setup,I think taking all aspects of shooting into consideration,it's a winner that's for sure.
Go to the Shooters Calculator Pick kinetic Energy and joules go look up the good stuff 6.5 Grendel In Underwood ammo or Hornady 123 gr SST and 6.5 Grendel Spanks the 6mm everywhere I searched for good ammo
Great cartridge but can't find it yet alone afford it. I'll keep reloading my Grendel.
I love my grendels all 3 of them. 12” 16” and 18” but that 16” barrel is about to get pulled for a 16” or 18” faxon 6mm arc barrel. I was wondering what if you put the 107gn Sierra match king in the Grendel how it would stack up against that 108gn eld. Although they don’t make factory 107gn Grendel loads. But I’ll still be bringing out the Grendel for the deer. I won’t be shooting deer any farther than 300yds and I know for a fact that 120gn federal fusion will drop a 160lb white tail in its tracks from 220yds. And ima actually be trying out the new Barnes 115gn vor-tx this year too. And as far as the acss reticle I’ve got the 3-18x hud dmr on my 18” faxon Grendel and it lines up almost perfect out to 500yds with a 3/4” high zero at 100yds and the 4-14x Orion on my 16” Grendel works out to 600yds with the same zero. I’ve got the 1-8x on my 12” Grendel but haven’t tried it any farther than 200yds yet but I’m sure I can play around with the zero and get it close. Btw my 3-18x has the 223/5.56 reticle.
deon lee, Defender Ammo Co. in NC offers a 107 TMK, have not chroned it yet.
123gr Hormady SST 6.5 grendel has a BC of of .506, Where did you get your numbers?
I've got 3 different 6mm ARC's that I'm building but still waiting for the Hornady Precision Hunter to come out. Now I have a 12.5" 6.5 Grendel I built on a ZEV upper and lower receivers and a ballistic advantage barrel. I've taken prong horn, deer, and elk within 200 yds. So my 6mm ARC has a lot to of catching up to do.
This makes sense to me. I'm in soon as brass becomes available. Easy Choice
I can find .308 everywhere and within 400 yards, it is KING. 800 and 1,000 yard shooting will never happen on the east cost in the woods. .308 Wolf military surplus is available for plinking too .
Wonder if that's sweet tea or maker's mark in that glass lol
Yes
Finally somebody was able to give real answers about this round👍👍
What do you think about the 6mm ARC handloaded with a 70 grain bullet for coyotes? Do would expected speeds be according to your research and do you think it would have problems feeding?

The margin of error is so close that a long range most hunters can’t accurately call wind to make a difference I own both 6.5 Grendel and 6mm arc and love them equally they the most efficient cartridges on a ar15 platform so much that my BCM and Daniel Defense 556’s are relegated to home defense and steel plinking
You have convinced me about the 6mm ARC, however my 20 inch Grendel build has a muzzle velocity of 2580fps, which does add to its range. I might eventually get an ARC after some other projects and saving up some funds.
On another subject.....have you done anything more with the 458 socom?
I plugged in some numbers and found out that the 1-6 Raptor can be used with it out to 300 yards, the 18 inch ranging bars are 9inches for bracketing, and the wind holds are closer to 4 &8 mph.
2580fps with what bullet? I've been loading for grendel for years and I've never got 2580fps with a 123gr bullet in a 20 inch barrel.
excellent comparison. I suspect this a distinction that the deer I shoot wont be able to tell. The only caveat for hunters is to remember that rifles are not yet energy weapons; and "foot pounds of energy" while useful, do not directly corelate with ethical killing ability .
Yes! Loving to be able to see that data while hearing it. That's helps a great deal. Thank you!
I'm still not seeing a reason to get away from .308 for a default multipurpose rifle. Fighting ranges, hunting ranges, ammo prices, ammo stores and availability, et cetera, et cetera. For sniper work? Hmmm. Maybe 6.5CM. For your standard dude who may only own one or 2 rifles, I'm still liking 5.56 and .308; and for only one had gun, and only 1 rifle period, .308 BT Spitzer is still in the lead for me.
So I have been planning a 6.5 Grendel 11.5” pistol build. I wonder how the 6mm ARC will fare in a short barreled set up.
Not sure, I'm planning an 18 inch build here very shortly
Kotaboy32 Tactical looking forward to seeing your build
6mm Arc is very interesting ammo does need to catch up before I pull the trigger on it. Pretty much every caliber out there now. Let’s talk KPS and Sectional density. I know not everyone has powerful rifles for just hunting but my thought is it has to be able to drop what I am shooting at quickly and effectively. I say that but .243 does drop medium game animals.
Sir, I believe this is a viable option in the AR platform. I have looked at the data and believe in the reasoning for this. Some will look at this strictly as a 'wildcat'. However, as for Department of Defense and military, it will be as to what remains/becomes the standardized cartridge. For the average rifleman it is still 5.56mm.When the 6.8mm came out DOD did not adopt that (as a whole) for their cartridge. The popularity of this cartridge will be left to what ammunition logisticians influence decision makers to stockpile for the next 50 years or so. Nice video.
I agree with the majority of this entire review. All things being equal, real world velocities, and impact energies as they are, being within 100ft/lb at 300 yards, the 6.5 grendel will wound better than the 6mm arc. A 6.5 grendel has been proven effective on elk at those ranges. It is not my go to and I'm not arguing it as a suitable elk round but it has been used effectively as one. The additional frontal area of the 6.5 and added momentum from the heavier round tends to lend to better penetration in addition to slightly lower impact speeds tend to allow the rounds to hold together better under impact. I believe those taking elk typically aren't using 18" barrels, but it would not shock me either. A .243 is considered marginal on elk and in many places is THE MINIMUM legal round. A 6mm arc is quite a bit less powerful on paper than a .243 however it does far better in shorter barrels. That said, the 6.5 grendel is considerably more potent as barrel lengths reach the 20-24" range pushing the same loads at 100-200 fps faster than the 18". And given equal impact energy, it SHOULD be a more potent round on game due to the extra diameter.
All that said above, inside say 350-400 yards with 20-24" barrels and inside 300-350 yards with 16-18" barrels, both rounds are fantastic on deer size game. And you'd likely not see any difference in on game performance. As game gets larger, the bullet diameter differences, especially if more durable projectiles are used, will lend itself in favor of the 6.5 grendel pretty soundly. Both rounds allow for far more effective practice and better shot placement due to that to the average shooter so they both in a way punch well above their "weight class" and that's very good for both Hunter and quarry.
All in all, very good content. Well done and thorough. Thanks!
love the information.Thank you
Your Grendel velocity is low. I am getting at least 100fps faster out of my 16in. Are you selling the ARC?
What ammo are you shoot before you make a comment of selling something.
@@kotaboy32 no accusation here but he's right about the Grendel velocity. That should be closer to 2480 or so with the factory 6.5G 123s.
