I have two buddies that are treasure finder nuts. One goes to UK every year to detect. UK govt gets first crack at anything found so he don't get to keep much. Anyway they do the local lakes when they are drawn down for winter. They bring me coffee cans full of sinkers and jigs they find. I got to much of that kind of metal laying around. I'm not as anal as some with my bullet metal but I like uniformity and you can't have that melting random scrap. I'm shooting all either revolver target loads or LV rifle 25/20 through 45/70 so I never have to go beyond a 50:50 lead/ WW alloy, with a 20:1 tin added.
