I use tire weights a lot. I also have some pure lead for making HP's softer for expansion. For straight tire weights, I use a 5 gallon bucket with water in it. Put a towl in the bottom so getting the bullets out is easier. The quenching hardens the bullets to a BHN of 12-18. I lube with ALOX, size, then lube again with ALOX. Clean bore all the time. ALOX is a good lube, and lubing the second time (after resizing) seems to work for me. Have found no leading at all, just simple clean up after and ready to go again.
