1 in12 twist barrels

[2700xx]

I have the Corbin bullet swage setup for making jacket bullets from 22lr casings. They shoot well in 12 and 14 twist barrels from bolt guns but the jacket is too thin to push thru 7-8 and 9 twist ar barrels, at 223 speeds some of the bullets come apart in flight. Anyone familiar with someone who makes a decent 12 or 14 twist ar barrel as a stock standard item that's not special order or expensive. Thanks for looking.....

Green Mountain and Brownells military barrels both have options with 12 twist and they are decent barrels. Stock is hard to find on pretty much everything right now though

I also would call Keystone Accuracy. They may have something, or if they made one they have options for blanks that wont cost much more than a standard Green mountain etc
