I have been reloading for 4 years now. My wife and I prefer to shoot hard cast lead. 9mm cal. The other day my wife and I went to buy bullets only to find that we had to go to 4 different places to find a limited quantity. and the price went up almost double. So we decided to start looking into casting our own rounds. i have a lee single stage press if that means anfthing on this. my question here is what do we need in order to do this??? thank you ahead of time.
