In my younger years I have cast thousands of bullets for the .357, .41, .44 mag and the .45 ACP. I used wheel weights most of the time. My question is how are you smoking your moulds? If you are using a candle you're not only smoking your moulds, you're coating them with wax. Lubricant of any kind kills the mold's functing. In my day, miners carbide lamps were available. Today you might need to use wooden matches. By the way with my Lyman and my RCBS moulds I have never needed to smoke them.
