Micksis86:
I have cast thousands of bullets using stright wheel weights in calibers .357,
.410, .429, .452 and 454 and sizing them to the sizes listed. I shot full power loads and I never experience leading. Occasionally I had light streaks of leat the were removed with one or two passes of a bore brsh. At one time I used gas checks but soon did away with them.
