[QUOTE="Tidesloe, post: 3013715, member: 47761"] I fired 5 fireforming loads in a new chamber that’s a cartridge necked up from .30 to .33 and shoulder from 35 deg to 40 deg. Part of determining if my cases expanded to chamber dimensions after one firing, I removed my firing pin, and I have a fixed blade extractor to see at what point my brass chambers without resistance. I’ve had to bump the shoulders .008 to get the brass to chamber without resistance. I’ve done various things to try to determine what may be causing this. It seems to be a problem to me. Anyone run into this, and what was the cause, and final outcome of it? Thanks! [/QUOTE]
