A long time friend AND gunshop owner has a fab shop in back as well. He cast boolits too. He made this once from drops from some 3 X 1.5 channel. It's 4.5 inches long.
That ingot is 5#, not filled out because the mold was cold, and I was pouring from a lee 4-20, not much flow. He borrowed it to me for when I re-melt all that range lead I have to do. My job is to test it, then I might make a few more!
