Primers are flush, firing pin hole is clear, 002 on shoulder. Never shot factory loads
Agree with Dusty Noggin on the 3 pressure signs - looks to me like this case was fired with a high pressure load and expect a 4th pressure sign would also be present - that being significant case head expansion. Its possible that even though you bumped the shoulder back .002 the case head is still too large and even though it chambers it would still cause the stiff bolt lift/extraction of the empty case. That primer thing is weird - looking forward to answers from others on thatyou sure you posted the right picture ?? the pic looks like a fired brass .. with 3 different pressure signs ???
that high pressure extractor plunger mark or peirced primer or swipe .. too hot !!
that is when, upon removal the brass so stuck to chambered wall that the open cam action smears the back of brass .. what is your powder and charge
Was writing my post when BoomFlop's came in (agree with what he said).My guess is a very hot load with obvious signs of over pressure and case head growth that the die cannot resize.
There are a number of people experiencing sizing issues with the PRC case. When designing a chamber, brass, and resize die there is no one size fits all. We want good hard case brass, but its harder to size. We dont want sloppy chambers either. I have experience with designing reamers with...www.longrangehunting.com
