Cheers Simon, when i came to see you a couple of years ago for you to service the reg you said it was your original design so id say the MK1 reg.
problem im having is when i go over 775fps(8.44gn) or higher it gets even worse accuracy goes to hell, gun kicks more so ive always set the hammer to 760-770fps, reg works superb very consistent over the chrono.
The only thing i can think of is the plenum needs more capacity?
