Ok measured the chamber and it is indeed 2 7/8 but is really tight. The shell will go in till about 1/4 inch is sticking out and it seizes up. Checked the shell length and they are all uniform at 2 7/8 length within a few thousandths. I have a RCBS rock chucker press with the removable 7/8 14 bushing. Think I am going to do some measuring and attempt a sizing die. Can't find anything commercially available.
