I acquired several 5 gal buckets of scrap lead from an indoor range facility recently and have cast some of it up after smelting.
At first try it didn't fill out very well at all no matter the temperature. I added approx 1/2 lb of type metal per 10 pounds of range metal to the mix. Now it casts beautifully and shoots well.
I water drop because I don't have room currently to spread boolits to cool. They will not quite scratch with my fingernail but don't feel as hard as straight type metal.
Most of the range scrap is either jacketed or cast. There is also a considerable amount of 22 rimfire in there. Definitely no rifle, shotgun, or magnum pistol rounds(not allowed at this range).
I do not have a testing ability at this point other than my finger nail. It hasn't been important to this point.
Mostly just for the sake of curiosity, I would like to get opinions of what I might have for an alloy here>
Thanks
