I have a load that I've worked up & chrono'd as follows: 9mm PD FMJ - 115 gr Power Pistol - 6.1 gr Win SPP OAL 1.130 - 1.140 ( My goal was 1.135 and due to component variables these end up in the range). I've been using these loads for some time and have worked well. I've been loading lots of rounds and this morning noticed that the OAL has fallen to somewhere between 1.120 - 1.129. Should I have safety concerns shooting these? Would you pull all of them? Thanks!
