Do you guys sort your wheel weights? I spoke to the guy that makes the littleton shotmaker, and he said you have to sort your wheel weights and know which ones to discard. He said ones with paint, and ones with blunt ends(which most I found were painted) should not be used. He said they can ruin casting equiptment and is hard to remove if at all. I sorted one of the 6 pails of ww's I just got. Do I need to do this for bullet casting or using sinker molds? If I do which weights need to not be used from your experiences (shape, markings, etc). I would hate to ruin a mold. Any help would be much appreciated.
