I have an electric pot that holds ~ 65 pounds of lead. I will smelt a load, pour into ingots, get one of those analyzed (by me!) and then make the alloy I’m after. Right now, I am really happy with 96-2-2. It seems to work with all my pistols and rifles. So I have made up 3 lots of ~ 65 pounds.
I also powder coat and am not currently shooting high power rifle loads.
