I've had the Gunnar for a few months now, It was doing some weird things on my last few outings, and I haven't really had time to troubleshoot until now. It seemed like it was shooting erratically, I could tell by the sound of some shots, and could see on the target where the shot would drop quite a bit. It wouldn't do it all of the time, just maybe once every 8-12 shots. I took it out today with a chrony, and verified very inconsistent shots. Here's a pic. My thoughts are possibly a regulator issue? Or is there something else I should check? I also noticed maybe one or two times on my previous outing, that the gun would not fully cock. I made sure that I was pulling the cocking lever all the way back, but it's like the bolt would not "catch" right, and had to be cocked again which of course caused a double feed...Again this only happened once or twice and may or not be related to the erratic shot FPS. Gun is pretty much new, nothing has been changed or modified. I know Benjamin is pretty good w/ warranty issues. I would prefer to fix it myself though if it is a minor issue.
