257wby Report post Posted December 20, 2016 I have a question for you guys. On my AR, I have a 1:9 twist barrel that shoots lights out with 55 gr rounds, and typically a 1:7 shoots heavier rounds better. How does a bolt action rifle have a 1:12, and what can be expected from 55 gr rounds. Thanks Share this post Link to post Share on other sites
lancetkenyon Report post Posted December 20, 2016 A 1:12 should be able to stabilize up to a 60-62 grain bullet just fine. 55 grain will be great in it. 1 Share this post Link to post Share on other sites
Big or Bust Report post Posted December 20, 2016 Yup - 55's great in 12's... A 12 generally will not do the 62 ttsx, nor the 60 NP. Might get lucky though... Sometimes a 65 SGK or 64 PP will... More twist is never bad.... Share this post Link to post Share on other sites
dse Report post Posted December 20, 2016 Are you looking to buy a bolt gun, or already have one with a 1 in 12? There are several bolt rifles that come with a 1 in 9. Share this post Link to post Share on other sites

L Cazador Report post Posted December 21, 2016 You're stabilizing length not weight. Copper bullets like the Barnes tend to be longer so a 12 twist may not stabilize such bullets in a given weight range. Contact the bullet manufacturer for the best twist on a given bullet design and weight. You can usually overspin a bullet and still get pretty good accuracy as in your 9 twist with 55 grain bullets. 1 Share this post Link to post Share on other sites
