Good morning, I just bought a .223 with a 20” barrel with a 1:9 twist. It’s been a few years. We all get busy. Any chance of you making a Part 2 for that video? You did a great job on Part 1. I was thinking about sighting my rifle in at 100 yards with 69grain match ammo and then just plinking around with 62 grain. I would use the 69 grain to hunt with. What do you think? Thanks for your time and expertise.
That will def get the job done for you. You’ll get some good velocities out of that 20” barrel for sure! Thats a good zeroing plan. Also, with a 1:9 you can accurately plink with anything from 45gr on up! I’ll be doing that second part soon!
@@Warthog71 I know you are a busy guy and I don’t want you to feel like I’m manipulating you; however, you have a knack for explaining things in a basic but complete way. Your use of visual aids was crucial to me understanding why I would choose a twist rate, which led me to realize that performance would be accentuated by 4 more inches of barrel. Thank you.
Poor choice. Added speed on a 20" barrel and the length will over stabilize just like running a 1:7 would. Run a 1:7 with 77 grain and you wont be able to distinguish bullet holes at 100.
@@matthew33721 You are wrong again. You joined the conversation a year later and are speculating again. You get your bullets from a box. I make them. Don’t have kids. We don’t need your blood line being continued. Merry Christmas simp.
Thank you for this information I have a 223 wylde upper with 1/9 twist rate on a Anderson am15 and have a case of 5.56 62 grain green tip ammo but now know it will perform great when needed
This is why I buy 1:9 twist barrels and why they should be the standard over 1:7. Look how many different grains are covered under the 1:9 twist rate compared to everything else. And look at which ones they are. 55 and 62 grain which are the most common, easily accessible and cheaper rounds on the chart. It’s a no brainer
@@lateralus1972 For an SPR that you want to shoot more long distance with I would go 20 inch barrel for added velocity and accuracy. The rotation of the bullet doesn’t change much at all from different barrel lengths.
They taught us that they switch to 1:7 twist with the M16A2 because it stabilized both 62 grain M855 and the heavier tracer ammo. They knew 1:8-1:9 were better but they found 1:7 acceptable. And the civilian market just ran with 1:7. You are correct 1:9 is the best all around twist rate you can’t get.
All mine are 1/8 for 5.56…… I shoot anywhere from 52 grain eld match handloads to 77 grain sierra tipped match king and other then the poi change they shoot them very well…… they both consistently shoot one ragged hole….. I also shoot a lot of the 60 tmk and 70 nosler rdf….. so yes this is why Im a huge fan of 1/8 IMO its the best…….
I gave up on worrying about twist rates along time ago. I didn’t buy a 243 with a fast twist rate because every Internet forum said they wouldn’t stabilize light projectiles. Glad I didn’t listen. I have a 1/8 and 1/9 twist in .243 that both will shoot .2” to .3” with 55 grain and 60 grain hand loads. Same with my Fast twist POF in 5.56. It shoot light bullets super accurate. If you a good hand loader imo you will find a decent load with just about any projectile out there.
Nice video! My AR's have 1:7 twist and I practice at 50 and 100 yards (that's the farthest range we have in Hawaii) with 55gr M193, but have my SHTF mags loaded with 77gr.
Mine has 1:7, too, but mine prints nice groups consistantly under 20mm at 100m with Geco 63grs Target FMJ. I think precision only given by a "correct" twistrate vs. weight is not that huge topic unlike many creators claim.
Had the best accuracy with 1:9 16"match barrels with weights up to 69 GR. My 1:7 556 barrels with 55 GR are not as consistent when you go over 100 yards which gets more problematic at 300 and 400 yards. Those 2-3 inches of deviation with wind, temp and other factors can make that score difference. Cannot afford to shoot the 69 GR bullets in large quantities but they sure are accurate. Settling on 1:8 18' three gun match barrel as my next replacement purchase but sure miss my 1:9 match barrels.
1/7 twist is most common is pistol caliber and SBR rifles with barrels under 10". So 55 and 62 grain is just fine, considering shorter rifles are not used for over 300 yard shots typicly. Most people keep their shots within 100 yards.
A lot of 1:8 higher end barrels for more refined less "duty" oriented AR-15s recommend higher grain rounds for better accuracy at range from what I've seen. Criterion, whoever Radian uses, JP, etc.
I have a Panther carbine 16 with 16" barrel 1:9 twist. I am designating it as Recce rifle. been trying to determine this exact thing. best round for this barrel its HBAR chrome moly. old school DPMS manufactured in 2008.
lol just picked me up my new and 1st AR today. My local shop was running a promotion that the Colt M4 Carbine came with a really nice carry bag ,3 mags and some a 50 rnd box of ammo and was able to buy another box with the purchace plus another 50 rnd box for the range and free lane on the range . It was a decent deal ! I real like it and now im already looking to get a stripped lower and do a build......this rabbit hole is a deep one but i like it, lol!!!
I like the 1/8 twist rate. Please, if you have a 1/9 try all bullet weights from 55-77gr. My 1/9 shoots heavy stuff great as does my 1/7 shoot 55gr. good enough. My 1/8 is a happy medium.
Uncle Joe gave me an ARK 47-15-308 assault rifle shotgun. It has a twist rate if 1:-1,000,000 it is heavier than a bag of bricks and bruises my shoulder when I shoot it
You must have the shoulder stock adapter that allows you to shoot a bigger bullet as well.. damn gun guys. And magazine fed i assume.. makes the damn thing fully semi auto. Sounds like the danger zone pal😂😂
For my 20" 1: 9 barrel i use 55grn ball for plinking, 64grn Winchester Deer Season for home defense/hunting, and i have a sh!t-ton of 62grn green tip stashed for SHTF.... my rifle eats this ammo like candy😁
Me too! The truth is, 90+% of shooters have a ave distance of shooting under 100yards. Just about any weight projo will get the job done. It’s just a matter of how far one is will to travel to track a a wounded animal to harvest if the shot isn’t as accurate as intended, I guess.
Here's a thing, the faster the twist, the heavier (actually longer) the bullet it will stabilize. But, the lighter bullets are still stable. Physics. If your lighter bullets "come apart" or "lose accuracy," blame bullet construction, or the individual barrel.
@Warthog71 there is so much misinformation on the interwebs. I read one comment that said, "It's the air being pushed out of the barrel ahead of the bullet that causes recoil." Funny
So true! What is most available and what is cheapest and that would be 55 and 62 grain which is why I buy 1:9 twist rifles. That’s not going to change either
@ 3:00ish “the faster the Spin, the higher the revolutions per minute leaving the barrel, That can mean more velocity “ Not a troll, but please explain. Everything I’ve learned says rpm is not correlated to muzzle velocity.
Think of it this way. If you are running a 16” barrel and your velocity is 2400fps, then switch to a 18” and get 2600, 20” 2800, 24” 3200. It’s because the projectile had more of a chanc to increase its RPMs through the barrel The reason why ammo is rated with velocities from a 24” barrel, is because it offers the Max velocity by way of spin. Hope that helped brother🇺🇸
@Cerra you are correct. Muzzle velocity is directly related to the length of the barrel, at a certain point. Bullet rpm as induced by barrel twist rate does not affect velocity.
Twist will not matter at spitting distance--inducing a yaw in projectile inside of 100 yards can prove devastating-sometimes the process is over thought-key is to decide what your intentions are then buy/build to meet your needs
my 1:7 shoots 55gr. with more accuracy than 62gr. I think it depends more on brand. Winchester 55gr on the same barrel just fly away and I can hear the bullet says "good bye target"
I agree. The left is pushing their timeline up with what we they are attempting to accomplish. We were told to watch the water and now Clinton’s ship is grounded in the straights

You dont shoot over 50 yards then lmfao
1:8 twist is easily explained as one full rotation per 8 inches of barrel

I love heavy for caliber, better terminal performance and better BC for longer shots. All of mine are 1/7 to accommodate heavier options.
1:7 20" with 77grain reloads. Coyotes dont stand a chance under 300
I use mine for late season doe management. Half moa up to 200 perfect off button shots every time
@@matthew33721 I like both 77 Grain OTM and TMK. I also use the 75 Grain Tipped rounds as well. Always less than 1 MOA at 100 yards.
