I found myself to be very lucky that I have a local scrap metal dealer. I pay whatever price he quotes. My good luck that he is an old guy like me who remembers how it used to be. If I want to buy COWW he will smelt them into one lb ingots or disks that fit the bottom of one of his frying pans. He also has some soft lead if I want it. I don't mind paying for lead. It's just another commodity. I buy tin from Rotometals as well as some Lyman #2 for higher velocities. Been experimenting with softer alloys like 49% Pb 49% COWW, and 2% tin for powder coated boolits. Those things are wonderful. They take high velocities without leading. Hope for some expansion.
