RE: 480 ruger question
You have the choice of P.A.S.T. shooting gloves,hogue grips,and might consider porting it or having a muzzle break installed. Proper fitting,recoil adsorbing grips are a must. I don't understand the recoil doing that to your hand unless you might be gripping it wrong or the factory grips just don't fit you at all. It don't bother me when shooting full house loads of .454 casull. Another idea is to work up a slightly reduced load when reloading.
