Re: .458 winchester cast bullets in the Ruger #1
For hardness-- drop the slugs hot right otta the mold into a pail of cool water. That'll harden them to the range of linotype. Most likely sizing isn't going to be needed.
3031 is good powder for the 458 for sure. Another tac is a caseful of slow fuel just mildly compressed. THat stradegy is something slower and possibly easier on the shoulder. Those 500's don't have to go 2000 fps to do the job-- the 45/70 is an excellent killer at 5-700 fps slower.
Pat your first job is determining throating on your gun-- dia and length. Match the dia with your slug and try to seat that slug as far forward to the rifling as possible. Some 458's have long throats.Pat said:
