I got this hunk of lead at an auction. had no idea what the alloy is.

I smelted down and casted some up. I did something I rarely do, I got the mold too hot. if it was an alloyed lead it would be some type of frosting. the lead was also really hot. could not find my thermometer so I could not test the leads temp.

took two mins to cool the spur.

Corey, if you want to send me one bullet, I will do a hardness test for you and give you the BHN. This might give us an idea of tin/antimony content.
