Home Forums Hunting & Shooting Hunting Rifles .308 Win 1:12 Twist

The 1/12 twist should be fine up to a 180 grain flat base bullet at sea level, it will be marginal with a 180 boat tail though. I prefer the versatility of a 1/10 twist.

I tried 208 amax in my 1/12 308 at 4500' and it wasn't as accurate as it was with the 168 amax I suspect they were on the verge of being unstable. Montana Marine has had good luck with the 208 in his 1/12 and that is why I tried them.
