[QUOTE="Rifleman513, post: 1182300, member: 32318"] I should have been more clear. It's a 375 Black Mesa Express, it was developed about 6 years before Remington came out with their Ultra Mag cartridges. I know of others who are making their brass out or 375 RUM brass which just needs to be ran through a FL sizing die. Others who have loaded for it said the 404J brass was a lot tougher to form than the RUM brass and they could never get it to eject very well, they ended up with a lot of stuck cases. I ran a few old once fired 300 rum cases I had lying around just to try them out. 5 nickel plated Federal cases chambered and ejected with no problem. I then tried a new Nosler piece of brass and one once fired piece. Neither of the Nosler pieces would allow the bolt to close all the way. Not sure why one type works perfectly and the other won't.
