I recently bought a Savage LRPV .223 with the 7 twist barrel. I am trying to work a load with the Hornady 75 Amax. I have tried Varget, Rl-15, Tac, H 4895 with no luck. I have loaded c.o.a.l. from 2.39' to in the lands with no luck. Does anyone have experience with this rifle and this bullet? Looking for a place to start. I realize the 7 twist was designed for heavier bullets but have 600 75 Amaxs. I'm running out of ideas. The gun will shoot Berger 73 bthp like a house on fire. Thanks, Wade
