it's official: 1:8 is the perfect twist rate for your AR.

>b..but muh milspec!
stfu, 1:7 was chosen solely to stabilize retardedly long tracers.

1:8 is perfect for almost every caliber.
i wish manufacturers made .223 or .243's with 1:8 twist barrels.

if you're fine with not shooting 70+ grain bullets 1:9 is fine. 1:8 is perfect for the heaviest mag-feedable match bullets and works fine with everything down to tiny varmint exploders. from a purely ballistic perspective there is no reason to not chose 1:8.

1:8 might spin very light varmint bullets to fast and cause them to explode before they hit the target similar to the problems that occur with .17's and rainy days.

nope. even with an 1:7 twist this fear is exaggerated and a 1:7 twist spins the bullet over 14% faster than 1:8.
