Bought 200 pounds of home cast teardrop fishing weights at a garage sale some time back. Smelted them down and cast into small ingots and stacked them up for later. Later came yesterday. I wanted to mix up some 50- 50 alloy for pistol paper punching. Had assumed the old fishing weights were probably COWW but in checking with my hardness tester all samples were coming out 22 BNH. Was I pleased.
