I have read hotter primers do better with ball powders. ie CCI 450, Rem 71/2.
Ignites the powder most consistently and prevents hangfires.
Awesome video! Thanks sir. I love some 8208 xbr. My second favorite is 2520. Can get awesome velocities out of both with little pressure issues in my guns.
Thank you for this, it saves me having to buy all these powder choices for myself.
Interesting bimodal chart for the CFE223 pressure, that might explain some of the over-pressurization signs and inaccuracy I have seen when shooting it in a 22" barreled bolt gun... I have loads worked up for 60 gr bullets that are under the max charge from multiple published sources. It works beautifully in multiple AR platforms from 10.5" to 16" barrels but has seriously cratered out the pin strike in the primers when fired in the bolt actions and sprayed the bullets into groups > 2" at 100 yards. Thank you for shedding some light on this subject.
Those pressure graphs are very interesting. I'm sure there is a lot of significance to them. I'm also sure that those secondary pressure peaks are very important as well but how so I dont know. I hope you continue exploring this more seems like if you could understand the relationship with the secondary pressure peak and standard deviation numbers you might be on to something new and very critical. Just like with the humidity of the powder and velocity numbers which swing wildly.
Also the jrb favorite powder being blc2 was hilarious.
18 inch barrel, 77 grain smks 25 grains w748, no signs of over pressure, .4ish inch groups at 100, 2.260 OAL 2730fps. One of my favorites. Cfe 223 is good for 55 grains in my experience
I bought some Win 748 when the supply of everything started to dry up because it was available at my LGS. I was not expecting a whole lot out of it. It surprised me in a very good way with some great accuracy across a wide range of bullets.
Thanks for the video. 8208 is the best accuracy I have gotten out of my 223. It's my powder of choice now
Watched most of the vid twice. Alot to process & disgust. But great information. Appreciate the detail & diligence. Thank you. Well done.
Thank you. I have always wondered how much different powders perform compared to one another. I was very surprised how different the pressure charts were.
TAC and AA2520 seem to be the most common ‘go to’s’ as far as ball powders are concerned. Would love to see an in depth shoot out between the two that compares the velocity, pressure, and accuracy. Love your videos! Thanks!
Here lately it's more of a matter of 'what can I make work' rather than 'what's best.' That said, I tend to use H322 a lot in the .223 because it gives good accuracy although not top velocity, meters well and most importantly, I have a substantial amount of it on hand.
Nothing wrong with that. You have to use what you can get a hold of. I have been trying to add to my powder library when I can but a lot of these I only bought a 1lb for testing. I was hoping it would give some guys starting out of an idea how things "may" work out if they can find one of these. Powder valley has had tac in stock pretty consistently lately, so I regret not putting it into the test, but my crystal ball has never worked that well either.
Loading 10 mm with 777 and cast lee 175 grain rounds. Looking to load black powder in rifle next. How well can u be prepared
As others have noted, a great deal of info packed into a short time. Nicely done! The thing that grabbed my attention was the large difference between published data and the results presented. Has this been noted and reported by others?
Clearly with a shorter test barrel you are going to loose some velocity but some powders are worse than others. Largely this should be a function of burn rate, but you will see lot to lot variation with the powder as well. If it was powder variation I would have hoped to see evidence of that in the pressure data though. Every time I see BLC-2 results I always just think of JRBs distaste for it, but the pressure graphs were all over the place so its no wonder why the accuracy was poor. (If you remove the vertical it wasn't half bad)
Always appreciate the information in your videos. XBR8208 is one of my most accurate, but slower, powders for the AR platform.
23.8 of IMR 8208
77 MK
LC brass
CCI 41
2750 fps in 18”
23.3 slightly less vel but better accuracy
1:7 twist
I really appreciate the side by side view of all the plots of velocity vs charge weight. In that view, it would be especially helpful to have the Y axis consistent from chart to chart. Probably useful to have the X axis also consistent from chart to chart-- just pick axis values that accommodate the full range of your data.
Years ago when the 204 came out I ordered one. It's a Ruger M 77 mark ll . No one had any data on it . My Dad , who is no longer with us helped set it up. Went with BLC2 . In short order I was shooting one hole groups all day long at 200 yards. Sorry for rambling on. Love your channel.
Hi Kevin, Glad you like the channel!
Thank you for a very informative video. Have you thought about making a video about powders that like the different barrel lengths? Like in a 223 AR platform, 16-18-20" lengths?
Barrel length and burn rate are worth mentioning as those who shoot 223 556 could be have anything from a 7 to 24 inch barrel.
Generally I've found powders around H4895 work well for stuff shorter than 14.5 and the varget range for anything longer.
Vit N530 is the craziest stuff I've found for 556. Expensive, but man it screams.
Varget. Good luck ever finding that in stock anywhere
Thanks for the video. I caught that JRB comment, good one. I bet BL-C 2 would have won the velocity race if it was hot outside, that stuff was pretty unstable for me. Those bullets, that primer and 23.1 gr of XBR has been good to me in both 16” and 20” barrels. I get good velocity, good groups, roughly 10 SD and it’s temp stable.
Tac is my go-to practice ammo powder in 223, when I took the charge weight up a bit, it became just as temp stable as XBR according to my Lab Radar; it hasn’t had the best lot-to-lot consistency though so work up carefully. Great video
Glad you enjoyed it. I initially hadn't planned to do any content in 223, but I thought a small series where you can see a wide range of powder might be interesting. I really hadn't expected to see such drastic differences in the pressure profiles. I may do something similar with 55gr if people are interested.
Gotta love the Fin..
You have tested very much and I appreciate very much the depth you go into. Very data oriented instead of measuring what seems or felt so and so.
I would suggest to test temperature sensitivity. I asked VV about their powders and they could not yet give me any data, but they said that temperature sensitivity is very bullet and cartridge specific.
Could you test this yourself and set a test of, say, 5 powders and 2 or 3 bullets across 3 different temperatures? Whatever test set you devise.
Capturing:
1) Temp sensitivity, with function of bullet model in comparison
2) pressure differences, with function of bullet model in comparison
3) pressure difference vs. MV, so even if one powder gets HOT when it is hot, does it still ACTUALLY burn with much higher pressure?
Educational and interesting
You and Capt reloading bench releasing videos on the same day is great. Sunday night entertainment. My old lady absolutely despises you both. Misson Accomplished! I salute you both
Hahahahaha, thanks for the laugh!
The secondary pressure event might be the result of the double-based (nitrocellulose and nitroglycerin) property of the ball powder tested.
very interesting study, thank you for the informative video. Do you have the extreme spreads observed for the other powders? I think you only showed the ones for the best and worst groupings observed.
I have a very large project coming that will have that kind of data included.
77gr TMK and ARcomp is incredible in my 1:8 20” AR
Great. I literally just bought 1lb of BLC2 a few hours ago as it was the first time I'd seen powder for 5.56 since I started reloading. Brand new reloader and only planning on loading range ammo, so hopefully I won't have too many issues until I can find something better.
I am sure it will work fine for plinking but you will probably find choices you like better.
I have ran blc(2) for years in my AR's. Very accurate, although the powder isn't the cleanest. It does meter well.
55gr blitzking and blc2 shoot awesome, have 20” heavy barrel and 24”standard barrel rem700 they both group nice
Like rl 15 for 223 rem works real good 👍
The sierra data is milder for the bolt guns because it's a true SAAMI .223 chamber whereas the AR15 data is for a 5.56 chamber. Sierra doesn't show this as being 5.56 because they used an AR15a2 HBAR sporter as their test gun. Those 1990s pre-ban HBARs would be marked "223" on the receiver (per colt practice for all civilian guns at the time) but the barrel would in fact be marked 5.56 chamber 7 twist. So you'll have a bit less pressure with the longer freebore of the 5.56 NATO chamber in place of the saami 223 chamber, as you'd expect to see based on your reloading experience.
I use Varget/Shooter's World Precision and 2520 for 75 and 77 grain 5.56 loads.
223 data is always welcome. I know of two recent lot# of cfe223 that sucked for accuracy/s.d., crazy reading the comments that like the stuff. I have read good results on 4166, not for this test. Thanks for the video, keep the 223 content coming.
Some of the best 223 powders I have ever used are on your table. The following have a special place in my heart…. Varget, H-4895, AR- Comp, 8208 XBR, H-322, AA2520, SW Precision and R15. With that said I also have a bunch of CFE 223, Tac and H335 for plinking rounds. I have been able to make some very accurate ammo with Those powders as well but I prefer the first ones I mentioned. Surprisingly I’ve had great results with Win 748 also. My buddy loves BLC2 but it’s not a fav of mine. I would love to get around to trying Benchmark I just haven’t yet.
+1 on sw precision
My son and I burned 16 lb of Benchmark in 223 over a few years. For the 55gr weight class, (plus or minus 5gr) I never found anything better.
@@Wmbhill that is exactly what I want to try it with (52 smk and some 55 vmax). I had the opportunity to buy an 8lb jug during all of this. But being I have never loaded any I decided to pass and let someone that had known loads get it. Being it one of the extreme series I have no doubt it awesome. Every other one out of that series is great that I have tried.
Thanks for the video. Very informative. How do you measure the pressure?
Never mind, I see already answered that question!
Interesting video, I've yet to find a decent load for my Horady 62 grain FMJ with CFE 223, Varget, or Benchmark, out of 18" barrel. However, with CFE 223 my gun loves the 60 grain VMax, nice 1/2" ragged hole.
I'm struggling too with the Hornady 62gr fmj bt. I started out with similar loads used for nosler 62gr bthp which those grouped great. Got a good deal on the Hornady's in bulk and figured they would perform similar, I was wrong. Also shot out of an 18in 1:8. Back to the drawing board I guess.
Love that 23.7 gr cfe and that vmax does some damage to soft targets and they are pretty cheap
My 24-in barrel with a barrel break which I'm assuming doesn't count on my own Remington 721 action practically bags for slow powders in my 270 Ackley. With imr7977 I can get it up there pretty damn good we'll be on my expectations and far exceeding my satisfaction threshold.
This is the way
love this. Would love to see a .308 video detailing charge weights to barrel length on a AR platform. I struggle with finding a way to balance velocity, bullet weight, reducing first round flash from my suppressor, and accuracy. Seems like if you use a ever so slightly faster powder and slightly heavier bullet you get really good suppressor results but lack velocity. Any time i go chase velocity and accuracy I then seem to get alot more flash from my suppressor. its hard to find good data out there because none of it is made for shorter barrels on ARs (that I have found). All bolt actions or long barrels. been trying to use faster powders with light bullets to get full burn but still obtain good velocity but the workup is slow.
Hi Riley, might want to look at a program called GRT (Gordon's reloading tool) it's similar to quickload but it's free. You can input your barrel length and then see % of powder burnt. Faster powders will be where you will need to go.
Well my friend, choice or preference no longer dictates what we will be using…. Availability and Cost rule the day… If we’ll be able to get it at all. Godspeed 👍🏻
good video
Thanks Mike, glad you enjoyed it!
Loved the BLC-2 comment.
I about did a spit take. “JRBs favorite power” lmao
I was afraid this may have been too much of an inside joke, but I couldn't resist.
In my 223 wylde chamber 20" ar with 77grtmk@2.260 oal, 24.8gr cfe223 in starline brass and cci 400, 60* outside, sea level, I'm getting 2762fps. I suspect there is a bit of lot variance.
I’ve had some my best groups and accuracy with 55gr blitzking and blc2 🤷🏽♂️
Have you ever tested VV N133? I’ve been using Benchmark for many years and it been pretty good, but decided to try something else. Was just wondering if you have ever tried it?
Powder? What’s that? Oh, now I remember. Yeah, haven’t seen that stuff in years.
No H335??? Still a good test, as always- Mopar or no car!
Have you considered that the "secondary" pressure peaks may actually be false readings due to constructive interference from the pressure wave reflecting off the end of the barrel?
It doesn't make much sense to see pressures that high when the bullet is already most of the way down the barrel meaning the combustion chamber volume must be quite large and with how many data points a PT-2 setup gathers per shot, I could totally see it being a artifact of barrel harmonics instead of a real pressure spike.
IMO the easiest way to test this would be to attach multiple strain gauges at various lengths down the barrel and seeing if the secondary spikes line up or not.
I'm using a Savage Axisll withe the heavy barrel and we have always used IMR 4320 now that this powder is discontinued what would you recommend using a Hornady 60gr vmax for varmint hunting.
Interesting that powders vary in volume by weight, are dippers more reliable than weights?
👍👍
. Where did you get the wall mounts for your Dillion tool heads ?
They are from inline fabrication. I think someone posted that you can 3d print some as well, not sure how they would hold up, as I don't know the difference in the materials.
"How are you to know?"
Well, if the load data says X velocity was achieved in a 24" barrel and I'm shooting a 20" barrel... That's a pretty good indicator.
I've only been hand loading for a couple of yrs. Since my son is not shooting 1000 yrds with his FNH AR15 DMR, I tend to load what shoots the best group out to 600 yards. Right now, the load we have is Lapua brass, Federal 205 match primers (seated .002" below flush) Bl-C (2) at 23.3 grains will group a 77 TMK at in the low 2s and high 1s, the best group has been a 5 shot group in .178" center to center at 100 yrds.
24.8 grains of BL-C(2) have also proved to shoot 2s with a 65 Sierra spitzer boat tail bullet. But as everyone knows, every rifle likes a different load, this is just what his likes.
coal?
@Near Miss i would have to check and get back with you. I normally seat off cbto
@@gtroxlar8597 let me also know how much you are jumping it, if possible thanks :)
@Near Miss since they are shot out of an AR15 I dont measure jump to the lands i just want them to feed through the mag and shoot accurate. The 77s have a COAL length of 2.260. The Short Action comparators will not work on the 77s unless you seat them way out. The 65s have a CBTO of 1.788 which i suspect are close to the 2.260 COAL the 77s had.
@@gtroxlar8597 Excellent! Thanks!
This video respectfully "buttered my biscuit" great data
Hi Fred, Glad you enjoyed it!
With this cartridge, especially when fired in semi-auto, shouldn't the port-pressure of these powders be considered?
So which powder should I get?
I’ve been using alliant 2000-mr and love it. I’m a good ways above max charge but no pressure signs and decent velocity.
I use the same powder, a bit under max load using speer data for my speer bullet.
It's accurate which is all I can test for without getting a chrono. But I load for accuracy so fps could be higher but not as accurate so its not a big deal to me right now.
@@JamesSmullins I should have added this is out of a 223 Wylde barrel so it is able to withstand 556 pressures. I wouldn’t run this load out of a basic 223 rifle.
@@JSJTOUTDOORS same for me, I use the 556 load data for that reason.
I wish it would come back in stock, I've got enough left for about twenty rounds. 😢
As someone who's toying with getting into reloading (6.5 Creed & 300 PRC) powder choice can get overwhelming (what do all these letters and numbers mean?). Throw on top of that the fact that your fist, second, third, etc....options are likely not going to be available. I look forward to you doing a similar video looking at (reasonably) availably powders for medium - large cartridges.
Don't overthink it. Seriously. Reloading can seem like a bottomless rabbit hole with two hundred wrong turns. It's not nearly that complex. There are differences between powders, sure. But particularly for common calibers and loads like you're talking about, the work has already been done. Find some common loads that people are using for your purposes, whether your purpose is hunting or competition because those are different goals. Until you begin trying to push the extremes of what a caliber can do, almost anything can be made to work. Before you lose one second of sleep, decide what you're trying to accomplish with a given load. Then look for published load data which fits the bill. Get a basic benchmark for your rifle and then start tweaking. You don't need 101 options. You need a few basic loads that work well in your rifle based on the components that you can get easily and standardize on them.
I really really wish you would have tried H335...
I don't have it in my powder library at the moment. I am lucky to have as many options as I do.
What is the Formula using excel to get the case pressure?
Bar none the best .223 rounds I ever loaded were with Varget. If I could find it I would probably still be using it -- so it's H335 for now.
With Varget and a 75g Hornady bthp my White Oak barreled AR shoots .3-.5 inch groups. 8208 is just under an inch
+1, Varget seems to be the catalyst for accuracy for a variety of bullet weights for me as well. It seems to be very tolerant to OAL and bullet weight changes as well.
Interesting that you don't use any of the powders I use to reload for my .223.
Why did you leave out H335 for the 223 ??
great video. you're doing 77 grainers but not TAC? that part confused me
Just got some tac. Plus 10 powders at a time is enough to keep up with.
I always found cfe223 only shot well at higher end of powder charge
same here.
Please do tell where anyone can find Varget??
A word of caution, those ball powders are not temp stable if you are doing load development you better do it on the hottest day you can find. The velocity and pressure swings will scare you.
TAC excellent powder with 77gr at 24.0
My 2 cents. Use new or once fired name brand brass. I don't like Wolf brass. Do not pickup range brass. Clean the brass every time. Get an electronic powder scale. Start low and work up. When feeding an AR rifle check that the rounds will feed smoothly without pushing the bullets into the case. If it does - fix it. Keep track of the number of firings for each batch of brass and label it. When splits start to occur throw out the whole batch - after firing of course. Annealing may work but not always. I have loaded and fired brass 6 times without issues.
Being a shooter and hunter I am in the process of developing and good 223 Deer load for my AR15 18inch SPR Barrel been working with Barnes 55 and 62 TTXS and Hammer 70grain HH bullets using both the Hornady GMX and Barnes TTXS loading data ( couldn't find any GMX bullets ) Being a hunting load not looking at bench rest accuracy more on the terminal performance of the bullet hoping to push the Barnes above 3000fps and the Hammer at 2750 to 2800 fps . My powder choice is Varmint, AR comp, and Accurate 2520 any suggestions you or anyone else would have I am all ears.
I think JRB had pretty good luck with the sierra 65gr ruclips.net/video/l1gnU0rxYCQ/видео.html if I remember it was pretty accurate as well as effective.
Here in the real world , I am lucky to find any powder or primers for use in 223 .
Hi Bill that is kind of the purpose of the video of understanding that there are options out there and possibly give some expectations. Some people have the idea that if I can't find varget I can't reload. Meanwhile powder valley had Tac in stock most all last week (and still does as I write this comment). Any given day you might run into a new option and hopefully you can see how it "may"
work. I have seen primers in stock at my local Cabelas of all things a couple times now, not for prices that people "want" to pay, but I try to worry about things I can control as best I can.
I wonder if that 2nd pressure curve is from flash over. 🤔
In the manual for the pressure trace it warns of this very issue. I need to do some more work in other calibers to learn more.
I think it was preordained that 8208 comes in a gold bottle lol. It's good stuff and as hard to find as gold
Agreed!! my 223 bolt has a 28in 1-7 twist and loves 8208 xbr.
Funny that stuff just sat on the shelf in Ohio until I just felt bad for it
I lucked into some more last week but it's not here yet. Hopefully next week.
I have found that blc2 to be a very versatile powder but not very accurate. Shot it out of the Grendel lever evolution is way better.
My 20” tikka bolt action loves BLC2. My 16” AR not so much.
How far down the barrel do you think that second pressure wave is?
I really don't even want to guess. I initially wondered if it was by the gas port so I picked up a adjustable gas block and shut it off completely and had the same result.
Did I misread the chart for Benchmark? Didn’t it have a flat velocity node towards the higher charges?
It does, oddly enough as I approached max it started so slow down a little.
I wish you'd included Winchester 748 and H335 in this test.
I am not a fan of BLC2. Just never had good results with it. Think I gave it away or just burned it up years ago.
Is the Sierra AR15 load data for 5.56 pressure and the bolt action load data for .223 Remington pressure?
Both data sets state 223 Remington
Is it just me or does anyone else think it’s bogus these companies use ridiculously long barrel lengths to give us velocity data? 24 inch 223 barrel?! Give it to us in a 16 and 20. 16 inch being the legal minimum for a non NFA item and 20 inches for the original AR15. I think it’s absurd I see 18 inch 300 blackout data when the cartridge was made for short barrels in pistol/SBR formats. 🤦🏽♂️
Buy a chronograph and test your oun loads , you can get one for a little over a hundred bucks !……..
Take a Chill 👉🏻💊
They have to consider the longest barrel that will be used in a particular caliber, if they didn’t… then everyone would be going ape 💩 crazy that they didn’t. Make sense?
@@nigel900 All they have to do is just state the barrel length with the date they give ! And once again if you reload ( buy a chronograph ) !
@@thomasdaum1927 Wouldn’t make a bit of difference.
Loading data is simply a 👉🏻Guideline👈🏻
@@thomasdaum1927 Wouldn’t make a bit of difference. Barrel length is only one of many variables that dictate performance… and the load data provided is simply a Guideline.
Have you heard about Willy the Bullet Man passed away yesterday may he rest in peace.
I had not heard. Very sad news.
How are you getting the pressure numbers
Hi Cory, with the pressure trace 2 system. I have a video on it here ruclips.net/video/KeMzq3ZepYg/видео.html
I love my tac
Lots of people have good luck with it and its been in stock at PV so I regret not adding it. My crystal ball has never worked very well.
@Bolt Action Reloading totally understand. I have 2 decent single digit SD loads with it for 308 and 223. 308 I'm pushing a 175smk and 223 I'm pushing a 53vmax.
The funny thing is is those numbers can change, not only with barrel length, but bullet used, seating depth, primer and even the lot of powder... So, this info is really only useful for your specific test and all the variables used. Not a great indicator of how good or bad a powder is in general (IMO)
While I'll agree you have to make assumptions with this data I disagree with there not being good information to make a choice if you want to invest the time in a powder and load development. The data showed how poorly staball 6.5 was velocity wise while being compressed while have low velocity. That shows me don't bother with this in 223. It also showed me how well accurate 2520 seems to work. Lower pressure relative while also producing great velocity. That's a powder I'd normally never try I just dont have alot of experience with accurate powders not some vendetta against them.
Yes you can use the same argument that well depends on all the other infinite variables but I dont think this was meant to be the be all end all factor what makes a powder good or bad. Even if it narrows down powder selection by 10 percent currently I find that extremely valuable.
I wonder what he looks like. I'm betting a cross between Paul harrel, garand thumb, and James reeves
There are very few people who load a bullet that heavy in a 223 , most reloaders who load this round ,,load it for varmit hunting ,,and for that most of the bullets loaded are between 50 and 63 grains ,, most of those use a bolt action rife ,,and a lot of those are over 24 inche barrels ,,this is great Imformation for the guys who have AR type rifles with short barrels ,, but all the other guys ,,you will have to do your own work
I don't know what the percentages are but a lot of people use the 77 in NRA Highpower rifle competition (200 and 300 yards). The 77 is seated to magazine length for rapid fire stages, the 80s are usually seated out a bit longer and used in the single load slow fire stage (600 yards).
@@billj5645 I don’t know that fact either but would almost bet money that for every one 223 that is shot in competition, there is 100 that never even thought about it. Lots of hunters and not many professional ballastitions, myself I have never shot competitions and been loading 223 since 1970
@@bobbygreen2291 Back to your point- I thought it odd that he wasn't using something 60 grains or less.
@@billj5645 the light bullets work real good and are very accurate for varmint hunting ,,however professional shooters have to have their loads worked to perfection and typically shoot a lot farther distance.
The Talking Hand I think also does financial vids.
I'm new to it and have a newbie question. As long as I follow safe amounts for powder charges and am using good brass can I substitute any brand of small rifle primer? As long as its of good quality? I'm trying to put something together given the scarcity of components.
Hi Gary. Check out this video and it will help you understand how different primers perform ruclips.net/video/a69VBkT_Mxo/видео.html
tx
Aren’t most 223 chambers now really 223 Wylde chambers and the max pressures is 62k as they can handle the NATO 5.56
Iirc the largest difference between nato pressure spec and Sammi pressure spec is more due to testing than methods than actual pressure
200fps below advertised... looking at you Varget. LOL
Hummmm. Head scratching.
I avoid powders that need magnum primers, hard to get and expensive.
. 0:45 powder reference
What is that press? It sounded like you said M-press, but that is certainly not a Frankford Arsenal.
But who is Fanny?
Well whatever. I managed to get one hole 10 shot groups with blc2 in a223 bolt rifle I have also had good results in 308 and 30-30. Varget is wonderful but I've gotten better groups with bench rest. Your working with an AR and any bullet over 68 grains to me is counter productive in my humble opinion. As I believe any velocity below 3000 fps defeats the purpose.
Reaally?? In my opinion, you go past 2800 and you start switching plain speed for accuracy and BC. And ballistic solvers agree with me..
-55grainers are for fudds or volume shooting.
-62 grainers are better but 90% of time much more expensive than 55s, with only small benefit in external ballistics.
-69 grainers are there to only give guns with lacking twist rate a better option than miserable 62gr.
-77 grainers are the god's gift, they have been designed to make use of everything a rifle has to offer: fly straight, wind resistant, good speed, optimized for mag length, excellent accuracy, deliver energy, oh lord thank you.
-80grs and above are for the holiest shooters only, do not touch them.
Can't say I got anything out of this video. Doesn't seem to be a point to it. I can see why volume under the curve might be good, but why would a secondary peak be bad? That's not clear to me.
When I look at powder I ask myself. "Will this powder meter well, and if not do I get compensated for time spent weighing? Does the powder achieve the velocity I'm looking for? Does the powder shoot consistent vertical groups over it's charge range? Is the powder overly temperature sensitive? Can I achieve acceptable groups with the powder. Is the powder known for pressure spikes? Does the manufacturer give us a consistent powder?"
Personally, I wound up using AR Comp for consistency with heavier bullets, and 2520 for velocity in the mid-weight bullets, and both for good accuracy. I could have chosen 8208 in lieu of AR Comp, but I don't know another powder that I could swap in for 2520.
I NEED MORE CONTENT BOLT ACTION RELOADING. 7 minutes isn’t long enough you Sir are constantly touching on ALL the questions that go through my mind. But I can’t wrap my mind around some of the stuff you talk about. I just barely grasp what your talking about and it really irritates me. Not your videos but the fact that I’m not completely understanding the information your telling me.
Hi Johnny, Well I hope you enjoyed it anyway. You can always watch it twice 😉. I have been trying to cut out all but what is absolutely necessary and see if the videos perform differently. I have to admit I have been working with this data for a while now, trying to figure out the best way to present it. It is easy to get bogged down in the pressure charts so I am trying to stick to peak pressure for the moment. If there is anything that you think I can do to make the data more clear I am certainly open for suggestions!
