It is claimed that you can water drop the PC bullets into cold water to increase hardness.

Paper patching looks like too much work unless I'm replicating a 45/70 or 50/50 round. PC looks easier. However, would a double PC be detrimental to bring a .309"cast bullet to .311? Another option could be to hone out a .309-200gr aluminum mold to .311 and powder coat to .312.
