For the guys tumbling to get the lube off. Why not just wipe it with a rag with some mineral spirits or such on it?
Ditto. I've always heard that tumbling live rounds leads to fragmentation of powder, which leads to faster burning, but that could be wrong. Whatever, I won't trust what the internet says, I'd experiment with a few rounds containing the exact powder I use. (And when I say "experiment," that doesn't mean tumbling and shooting to see if I blow my head off. I mean tumbling and then pulling the bullets to see what happened to the powder.)
