I have run out of all my scrap lead collected over the years so am buying the good stuff now. I bought Lyman #2 which they list as 90% lead ,5% tin & 5% antimony & is listed as 15 on the scale.I powder coat & gas check my faster rifle loads so want something a little softer. If I smelt it to 1# bars at 2 parts #2 to 1 part pure , my figures come out to 93.3 lead ,3.3 tin & 3.3 antimony. Can someone tell me the hardness of that.
