The other day I got my lee 430-310 FN mold in and decided to cast some bullets. I had my alloy at 650 deg. but seemed to keep getting frosted bullets. Is this normal where the mold does not have a lot of excess metal and stays too hot?
I cast some 358-158 RF out of the same pot with no frosting at all.
For some reason too the frosted bullets are undersized to the few that was able to cast that was not.
