I've started casting bullets for .30 carbine, using a Lee C309-120-R. It yields bullets that weigh 118 gr and measure .312, which seems a little big to me. I've sized about 60 of them to .308 and will start with those. I can only find load data for 100 and 110 grain bullets, and nothing for 120 gr cast bullets. I'd like to use Red Dot, Unique, or H110, and would like to achieve velocities low enough to avoid using a gas check. Any suggestions? I also have a question about sizing. These bullets were VERY difficult to push through the sizing die, some nearly lifing my fee off the floor. I started using a small brush after every 4 or 5 to clean out the die, and that seemed to help. Should it be that hard?
