Where do you buy lead wire for swaging? The cheapest I can find is RCECO for $78 per 25LB spool. I thought I saw someone in the vendor section selling lead spools at a good price. Now I don't see anyone selling lead spools.
Also, what is the "hardest" lead that is feasible to swage. I have Richard's Walnut Hill press and his dies. Currently I only have lead bullet dies for .44 and .45 diameters. I am interested in trying to cast cores for these and would like to know if I need to stick to pure lead or can I use something a little harder. Something like 50% pure lead mixed with 50% wheel weights? Or any other mixture.
