Fx Maverick setting hammer problem

[Marc.france]

Hello

I have problem to setting my Power wheels
tried a setting today, pressure 160/125-130, here are the results:
pw7:940 fps
pw6:920
pw5:890
pw4:800
pw3:980 loud popping noise
Pw2:980 loud popping noise
pw1:980 loud popping noise

What is my problem with 1/2/3 …. I dont understand.

My Maverick is .22 and 11grs hammer

So when you put wheel back to 7 it sounds normal again?  I had this with my wildcat as well and it blew the o-ring out of the breach.
