Let me put the rifling twist into perspective. Most all 30-06's have a 10 twist and most all 308's have a 12 twist. So the 12 twist for Colt's barrel is in line for the 7.62x39 which normally isn't suppose to shoot those real heavy bullets. Joe |

One showed up here today. It slugs a perfect .310 in the grooves. I was somewhat amazed to find the barrel extension has M4 cuts. Not coincidentally, a 16" Del-Ton - Wilson barrel showed up today as well. It slugs .3108 in the grooves. Interior finish isn't nearly as nice as the Colt barrel. I'm pondering turning a 13" twist .308 barrel just to see what it would do with the new 135g Matchking. |
That's funny on the Wilson barrel because mine slugs .3095 in the grooves. I knew the Colt would be .310 dead on the money. |
With very few exceptions, you'll find 7.62x39 bores at .310'ish and surplus/cheap commercial projectiles from .309-.312. My interest is in shooting 7.62x39 with a .308" projectile. I've been unable to find any currently manufactured .308 groove 7.62x39 AR-15 barrels. Surplus/cheap commercial ammunition is great, but I've long wanted to see what the 7.62x39 could do with a decent bullet and barrel. I received a 7.62x39 .3085 throat reamer and gauges a few weeks ago. I chambered a 9.25" .308 10 twist pistol barrel with it this weekend, will try it out over the holidays. A couple of 12 twist 17" barrels should arrive here sometime in July. |
