FAQ

Those who are looking for an answer to the question «Will a 1 in 9 twist ar shoot 62 grain ammo?» often ask the following questions:

🔬 Will a 1 in 9 twist ar shoot 62 grain?

"long range High Power shooters often select 1:8, 1:7.7, 1:7, or 1:6.5-twist barrels to stabilize the long 77, 80 and even 90 grain bullets used for 1,000 yard competition." AND "There is, of course, an exception: if you want to use loads utilizing the heavier, 75-77 grain match bullets currently used by Spec-Ops troops and other selected shooters, you'll want a 1:7 twist barrel.

🔬 Will a 1 in 9 twist ar shoot 62 grain ammunition?

The maker of the weapons (Colt/FN) said the 1/9 twist was optimal for the new SS109 projectile. The ARMY forced the 1/7 as a compromise so the rifle would stabalize the abortion of a tracer known as the M856, which is NOT an FN design. A 1/9 barrel, in MY experience, is the most accurate option when firing 55 or 62 grain ammo.

🔬 Will a 1 in 9 twist ar shoot 62 grain bullets?

Higher number twist rates perform better with lighter grain bullets, while lower number twist rates perform better with heavier grain bullets. Common wisdom for 5.56 NATO and .223 Rem. indicates those barrels with a rate of rifling at 1:9 or slower (1:10 etc.), in general, perform best with lighter bullets—60 grains or less. If you’re looking for a general-purpose, workmanlike utility player that pleasantly gobbles up anything thrown its way, 1:8 is a solid choice.

A 1/9 barrel, in MY experience, is the most accurate option when firing 55 or 62 grain ammo. Since I dont shoot the current en vogue rounds that are extra long and heavy, requiring a fast twist, I have no need for a barrel that is proven by the US Army to have a quick burn out rate.

Lastly, the 1:7 twist barrel is the “mil-spec” choice, as the U.S. military adopted this setup in the 1980s for its M16A2 rifle running a 62-grain M855 5.56 round. The 1:7 barrel, found in the M4, M16A4, Mk12 SPR and HK416, can stabilize up to a 90-grain bullet, and handles 70- to 77-grain projectiles across a wide spectrum of velocities. However, shooters will likely notice a serious deterioration of performance trying to run lighter 55-grain ammo through longer 1:7 barrels, as the ...

Conventional wisdom suggests this twist rate is perfect for bullets in the 55-to 60-grain range, though most will stabilize the common 62-grain FMJ rounds. If you hunt prairie dogs or coyotes with lightweight.223 bullets, this twist rate will do fine for your needs.

I think the general consensus is that the 1 in 9 twist rate is pretty optimal for the 55-grain and 62-grain projectiles. It's when you go into the high-60's and the 70+ grain weights that the 1 in 8 and 1 in 7 twist rates are seen to be beneficial. Regarding the 62-grain stuff, I hope what I've stated is good info.

In the M16A2 and M855 (62 gr FMJ) ammunition, 1 in 9 twist was actually optimum based on the velocity and length of the bullet. 1 in 7 was adopted however as it was felt that it was important to adequately stabilize M856 Tracer ammunition which was substantially longer.

The government research determined the then-standard 62-grain bullet was most accurate when delivered from M16 test barrels with 1:9 rifling. Unfortunately, tracer rounds were longer. They added 1.7 grains to their payload and became largely unstable downrange when delivered from the same guns. Further testing determined 1:8 was also good for the ball ammo. But it apparently did not display enough of an improvement to unseat 1:7.

Use only 62-69 grainers in both. The 1/8 is a sub MOA all day long while the 1/9 is MOA+. Shoot PPU and Gold Medal Match 69 gr the most. Both loads are .223 Rem and the 62 gr are M855 Green tipped 5.56x45mm. The 1/8 using the GMM is a 500-700 yard shooter while the 1/9 can only reliably reach 300+ yards.

1:9 twist rate, 100 and 200 yards, 35-grain bullets . At 100 yards, the light bullets in the 1:9 twist barrel worked reasonably well. Two different five-shot groups fired from 100 yards measured 1 ...

Why use a 1:7 twist when the only ammo it shoots well is the expensive 77 grain when a 1:9 twist will shoot just about anything from 55 - 69 grain pretty good? I dont understand what the appeal of a 1:7 twist is when it limits you to the most expensive ammo, and shoots everything else crappy. A 1:9 twist shoots pretty much anything pretty good. I am serious - has anyone else seen this happen? O. ORD Montani Semper Liberi. Full Member. Minuteman. Nov 12, 2005 6,147 22 Morgantown, WV, USA. May ...

1 in 8 inches is another twist rate trying to do it all in short barrels. From 14.5 to 18 inches the 1 in 8 will get you there with most 50 to 80-grain rounds. It’s fast, but not exceptionally so. A 1 in 8 will be perfect for shooting 62-grain rounds from a slightly shorter than average barrel. It still can stabilize those 55-grain rounds and ...
