I did mention possible Firing Pin problems in previous posts I.m glad the range officers concur, so what OAL did you finally come up withGot to the range and the aforementioned experiments lead to two discoveries: first that at .01 off the lands this rifle is sub MOA. The difference in accuracy between .04, .02 and .01 is amazing. Second discovery occured when a range officer took a look at what was going on. His opinion is that it is not a pressure issue. He believes it is a problem with the firing pin. We were joined by another range officer who agreed. I got some advice about ajusting a mauser bolt. So, all in all, and eventful trip to the range!
