Hey all, my father recently gave me about 15lbs of already cast and lubed pistol bullets he was given at an estate sale. A couple of weekends ago I was cleaning up some buckets of range lead and melted these down, as the lot I received them into ingots. I kept them separate so I could test the hardness. Well I did that last night and it is all 22bh. My question is, how much pure added to how much of this hard lead to get me in the 12/13bh? I have plenty of pure and tin in solder form.
