I know absolutely nothing about this (just the little that I read here) so don't think you'll insult me by stating something that's obvious. Heck, I don't even really know what to ask.
I'm thinking of expanding my casting to include 9mm bullets. From reading and using factory made bullets I think I'd like to poly coat them in an oven. But I assume I still need to size them. I was given some unsized 9mm bullets one time and they didn't produce groups, more like a shotgun pattern. I have a Rockchucker press and I've read about push through dies. I also read that they aren't made anymore? Yet I thought I saw them for sale.
Am I barking up the right tree? What am I not asking that I should be asking and what is the answer? Anything I'm missing? Please educate me or point me in the right direction.
TIA
