What NVhntr said.
Couple of fine points: DO NOT attempt to cast with hard alloys. Pure lead or pure with a very small amount of tin, say 60:1. If you’re planning to cast bullets bore diameter to maybe +001”. Use a BP lube, not ALOX. There is discussion in this in the LASC web site. Temperature is your buddy, or worst enemy. Cast pure lead or the 60:1 alloy at 800*.
