A little off topic, but i wonder if you guys know what the composition of the usual .22 long rifle bullet is. I believe a lot of swaged bullerts(and core) contain 2-3% antimony, but i really don't know about the .22 bullets. As far as the lead you are looking at, i smelt my wheel weights on a "Turkey Fryer" burner, in a plumber's pot( good luck finding one of them). I have a small lael that i can use to make ingots. I use two kinds on ngots, one is about a lb, and says Saeco. The other is a "corn stick pan" made of cast iron, ade for baking those little pieces of cornbread that look like ears of corn. Again, about a lb.
It really doesn't matter what you have as far as alloy, you just smelt a big enough batch to make it worth your time to alloy it. Lloyd is rright on the money. get it while you can, anfd possibly hide/ bury it. The epa needs something to do, and will come looking for it soon enough. For what it is worth, the dust is really the only thing dangerous about lead. Dust and oxides of lead. Be careful if you are in a range recovering this treasure trove to wear a mask, wash your hands after handleing, and befor handling you r marriage tackle or rubbing your eyes. Smoking a cigarette with lead dust on your hands is a good way to ingest it. Pouring molten lead, handling bullets, etc. are a lot less dangerous. dust and oxides really are dangerous. I switched the backstop in my private range to a sand trap on account of dust, and to make recovery easier.
