My foray into 300 blackout has led me to sizing cases with a redding pro carbide die set, and I'm having terrible getting finished rounds to chamber consistently and also fitting the case gauge. I started at touching the shell holder plus half a turn, and advanced it to 3/4 turn but that feels like a lot of cam-over and didn't really help size them more. I also started doing an"double tap" on cases being formed from used 223 brass, and that helped, but still missing something. What should I try before grinding down my shell holder .010?
