Hot damn! I cranked out 300 .44 balls in a couple of hours, using a 5lb cap. dipper pot .
I've never had but a single cavity mould before.
My son-in-laws father offered me a string of plumbers lead (that's a link of four or five 5lb ingots on a handle) in exchange for making him a bunch of balls. His father was a plumber so the lead cost him nothing, and even though I had to buy the mould, I thought it was a good deal.
Also, he lives in Maine (read- Powder Barn) and can get me black powder easier than I can.
