Took a hint from Bruce and tonights casting session included a shallow dish of water soaked rag which I touched at every cast to cool the sprue. I was using my Lee 429-200-RF double cavity mold and it cast very nicely this evening. I wasn't trying for speed, and probably was holding the tip of the sprue plate a bit long, but it seemed to help a great deal. Normally with this mold I have trouble with it being too hot. Not so tonight. I was able to make cast after cast after cast in an even rythem. And the bullets, Oh My how pretty they are. Nicely filled out, no shrinkage of the middle driving band from too much heat, no two toners. Just nice gray/off silver bullets without that frosted appearance which were consistantly filled out cast to cast. I have in past tried cooling this mold by touching the mold bottom to a damp rag, but found that to remove too much heat. Never occured to me to just touch the sprue plate . The more I read here, the more I have to forget everything I think I know.
