I'm having a hard time getting good bullets w/the range scrap I've collected. Mainly wrinkles & poor fill out. I thought the molds weren't hot enough but it dosen't seem to get better as I cast. Then I thought I must have oil in the cavitys so I've cleaned w/rubbing alcohol & acetone w/no improvement. I've added a little tin (pewter) & some wheel weight lead & that has helped some. It's still tough to get good clean bullets w/this batch.
