Yesterday morning I went out to the gun room and tried one of my .460 PP 405s in a fired case. It fit snug so I deprimed the case bell the mouth and loaded it. There is some tension on the boolit but a crimp is necessary to hold it in place. Before when I sized the cases I would have patches slide or tear from time to time. These loaded nice and they work in the gun. Should have been doing this all along maybe??
