Pure lead for tiny jigs, split shot and pinch-on sinkers. Wheel weights for medium and large sinkers. Zinc is saved for a friend that cast cannon balls. A local scrapyard has been my source for years. Lot cheaper than ebay and Roto Metals. I have some clean roof lead now and could have got lead pipe the other day. The horror stories I've heard is the ad says pure lead, what you get is wheel weight lead.
