I worry, too.
In the past I've acquired wheel weights for cartridge cast bullets and soft (pure) lead, from an area commercial smelter, for BP balls and bullets. Last week, I got some free soft lead from a new source: my dentist.
Lead is used to shield dental X-ray film. The foil used to be torn off the film and went into the waste-paper basket; but, now it's saved for "proper" disposal. Thin foil the size of a postage stamp doesn't sound like much, but it adds up. The dentist's offering yielded 4-pounds of ingots. That's enough for 350 .375 balls (US$30.63 [19.65 GPS] from Dixie Gun Works)!

Reason: added GPS amount
