Bronson,
Roofers use a good quality lead to, roof jacks are very soft lead. Another good one is X-ray rooms, when they remodel that's a gold mine for soft lead. Redman nailed it, the barter system is what us everyday guys use. A lot of times they'll even give it to you. I had tons of lead out of houses and X-ray rooms, I've even got some contractors who melt the lead into bread pans which I remelt as needed into ingots. I think I like making ingots more than jigheads, molten lead is mesmerizing, I just have to figure out that aqua regia to turn it into gold.
