Been kicking around a barrel for my AI (came 6.5 manban) and since I shoot a ton of 308, was looking to put a 308 barrel on it. ANything worth doing is worth overdoing so I was thinking of throwing a gain twist on it for 185 Berger Juggernaughts.
However gain twists are in short supply and for 30 cal they seem to be in the 1/8-9 range which seems very fast for 308 win and more appropriate to magnums (based on my casual knowledge). What is an appropriate gain twist for a 308 in the 175-185 gr region (I also like to shoot 178 ELD-M for Hornady and of course 175 TMK).
