Ok so how would I know when I actually off the regulator? I do have a Chronograph to test. Also, what is the common regulator pressure for a .22 pcp
If you fill with a bottle (or hand pump), fill gun, close valve and let the fill assembly charged (don't bleed). Turn your hammer spring in to "over strike" so that you will know exactly when it comes off. Shoot over the chrony noting the speed and the pressure. When you get a drop in FPS you will know when the gun is off regulation.
Exampe
3000 - 900
2950 - 901
2900 - 900
2850 - 905
2800 - 900
2750 - 903
2700 - 875
2650 - 850
With the above string you would see the reg is set to about 2750.
