Most of the "stick on" weights with adhesive are 99% pure I believe. The ones with the clips are differing alloys and amounts of basically some mix of tin, antimony, and arsenic for hardening purposes. Some are even made of zinc!
I melt em and let the clips float to the top with the zincones, which do not melt.. I use a magnet on a wire to remove the clips and then to skim the dross off. I personaly think ( noproof) some of the other materials with a higher melting point than lead floats to the top for skimming under low heat condition and "purifies" or softens the lead some what.
I have a listing in the buy it now section for .375" round balls for muzzleloading I have or slingshot ammo, just cause I make em and like to shoot alot. I don't what sinkers would go for, but I believe I have sold lead bars here on the forum for a little profit. I pay $40 a fivegallon jug locally
