I should have searched before I made my thread the other day.....

I am working up a load for 155 nossler cc with 4064. The goal is just a 100 yard plinker with decent accuracy. The rifle will not be shot much. My grandfather used one in the Marine Corps and he loves handling it when he comes over. I want to get him shooting it again. Has anyone messed with reduced loads? His shoulder can't take much anymore.
