What grips are you using on your higher recoil Contenders? I was using Pachmyr grippers, but have only had 30/30, .44 mag and .223 barrels. I've got a 45-70 on the way from one of the members here. I read somewhere that the Pachmyrs weren't suitable for this? Anyone know why? I have the standard rhynite grip, and will start with that. Thanks!
