Hello,
I have been casting for about 25 years. More off than on. During that time i have always used COWW. Now that I'm out of COWW, a friend dropped off a few hundred pounds of 97% Pb 3% Sb Outside of lead, what is it. Can it be cast as is? What do i need to do to use it for 223, 458 Socom, 45/70 and so on.
