wideopen231 Posted January 25, 2020 Report Posted January 25, 2020 Wondering what twist rrate works best with 308 in ar 10 with 20" barrel?
Radioactive Posted January 25, 2020 Report 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.
unforgiven Posted January 25, 2020 Report Posted January 25, 2020 (edited) The 4 I have are 1-10. 14.5", 16", 2- 20". Edited January 25, 2020 by unforgiven Brain fart
MikedaddyH Posted January 25, 2020 Report 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.
