Re: 300win mag with 1:11 twist bullet sugestions?
I'm not sure the 1 in 11 twist will stabilize a 200+ grain bullet in the 300 Win Mag. You would probably be right at the edge of the envelope. My 300 RUM would stabilize the 200 gr. AB with a 1:11 twist barrel, but I was pushing it at a much higher velocity. Buy a box and check for stabilization at 300 yds.
Other possibilites would be a 190 Berger (BC of .57), or 180 AB (BC of .507), or the 180 gr. Swift Sciroco II i(BC of .52) .
