Went to an auction (estate) today. Bought a bunch of what I figure is almost pure lead. Probably at least 40-50 lbs, conservativly. Maybe more. Gonna be castin some thumpers!! Sheet lead, plumbers etc. Pal of mine has a hardness tester!Plus melting pots, moulds etc. Got a nice set of calipers etc. Could have spent a bunch. the ol' boy was a reloader and muzzleloader nut!! Don't know what happened his firearms??
