Hi everyone, need you help. I purchased a seekins ph2 over a year ago and when testing the rifle out i noticed excessive case stretch. After some consideration i decided to further inspect. Later find out that seekins chambered this rifle incorrectly and took the rifle back and rebarreled/rechambered the rifle correctly (6.5prc). I then took those brass took all the measurements and decided they needed a little work to be able to work in 6.5 prc. Started by annealing and bumping shoulder slightly, then re-annealing and bumping should to where it just fit nicely in the chamber without a heavy bolt lift. Bare resized brass chambered nicely, however, when brass was reloaded i got a hard bolt close just to chamber it. The OACL is within SAAMI specs. Some things to not: Full length resizing with a redding type s bushing die and bullet seating with frankford arsenal universal bullet seating die. I am at a loss for words. funny it would chamber perfectly 2 weeks after resizing (waiting for any springback), then when loaded it has hard bolt close. Thanks in advance for any insight. Also using lapua brass.
