I use the scavenged range lead too, the cores of jacketed bullets are about 99% pure lead, very soft as the jackets provide the hardness. I use the recovered cast mixed with some linotype and ww's for my smokeless rounds. You might want to measure the cylinder bores before you invest in a mold, they can run from .451 to .455, in the last case you'll need a .457 mold, like I use for my ROA. The Lee works fine and is the least expensive.
