Free: Contests & Raffles.
Guys, thanks for the input. Some of the ingots did have markings. I don't recall what they were. I'm 99.99% sure the lead was intended to be used for reloading or muzzleloading as my friend's dad built his own muzzleloaders, and reloaded for shotguns and rifles/handguns. For those of you indicating you would buy some, what sort of quantities were you thinking? Feel free to PM if you prefer.
