[QUOTE="matthaias, post: 2004595, member: 115524"] I measured CBTO of my 7RM with Berger 168 VLDs using the Hornady OAL Gauge and Bullet Comparitor. I stopped pushing when I barely felt resistance, not jamming, and the bullet came out with the modified case 3 out of 5 measurements. I averaged this measurement and took 40 thousandths off, went to chamber a round, the bolt won’t close! I had to seat the bullet to 99 thousandths off the lands as measured by the tool to get the bolt to close without resistance. What am I doing wrong? I could understand if the brass wasn’t sized correctly or if the modified case wasn’t seated completely when taking measurements, but that is not the issue. I’m renting a uni throater to get my chamber to where the bullet isn’t seated past the shoulder. But I am still baffled by my experience. [/QUOTE]
