turborsx Posted December 19, 2014 Report Posted December 19, 2014 Does anybody know if a 18" .308 polygonal 1:11 twist stabilize heavier grain projectiles? 150 grain and up.

edgecrusher Posted December 20, 2014 Report Posted December 20, 2014 Should be fine for 175's as well
StainTrain Posted December 22, 2014 Report Posted December 22, 2014 Does anybody know if a 18" .308 polygonal 1:11 twist stabilize heavier grain projectiles? 150 grain and up. I own a barrel like this and it will stabilize pretty much anything you can get commercially available that travels above the speed of sound.
Cali_Ed Posted January 7, 2015 Report Posted January 7, 2015 Does 11.25 make a diffrence compared to just 11?
survivalshop Posted January 7, 2015 Report Posted January 7, 2015 The twist rate may have the fractional part & they just don't publish it as a 11.25 , leaving the .25 out . <dontknow>
