I have a Nephew that installs high dollar windows, doors from Italy. The garage doors use thirty-pound counterweights made out of pure clean lead bars. He gives me his extras.

The stick on wheelwrights they use on aluminum rims etc are pretty close to pure lead.
In the end tho by the time you gather lead from a scrap yard and get it all cleaned up and poured into ingots, it may be better just to bite the bullet and spend the money to get good alloy from Buffalo Arms or John Walters.
