wideopen231 Posted January 25, 2020 Report Share Posted January 25, 2020 Wondering what twist rrate works best with 308 in ar 10 with 20" barrel? Quote Link to comment Share on other sites More sharing options...
Radioactive Posted January 25, 2020 Report Share Posted January 25, 2020 1 in 10 or 1 in 11 probably most common but 1 in 12 works for 168 grainers depends what you want to do with it. My last 308 at came with a 1/10. Some others on here with more experience will chime in I’m sure. Quote Link to comment Share on other sites More sharing options...

MikedaddyH Posted January 25, 2020 Report Share Posted January 25, 2020 1 in 10.5" on a 21.5" barrel.... Crazy math thing ! Good luck finding one 😁 Seriously .... A 1 in 10 or 11 will be fine. 147 gr through 180 gr projectiles are going to shoot great. Quote Link to comment Share on other sites More sharing options...
