So as title says I got a cricket and I need help. The gun was power tuned in 2017 by Charlie Frear. I was able to turn hammer spring back some and get 880-900fps with .25cal 25grain jsb with a 20-25es across 10 shots. Here is where I need help. the first shot is 880 and all the following shots are 895-905 till I reload the magazine and the gun sits for a few minutes then it does it again first shot is always 20ish FPS slower then the rest unless I let the gun sit for a while between each shot. So I rebuilt the regulator thinking it was creeping up as it sat and after a rebuild with new O-Rings it does the same thing. Any suggestions would be appreciated
