243winxb nailed it , I knew that I had the head space too tight from bolt closure giving a smidgen too much resistance, just been lazy about resetting it
NO, My problem came from to much slop as the cartridge sits in the chamber. SAAMI calls it Head Clearance. If your having trouble closing the bolt you can not have my problem. Something else is causing the hard closure. Possibly an expanded web area from over pressure?
