pcp regulators

been a very frustrating week here,setting up the regulator for the pcp revolver,was told the Huma reg i purchased for the gun had been factory set at 1800psi,as i had origionally intened to set revolver up at the reg pressure,testing reg i found the thing was set for 22psi,which was of no use to me,i had changed my mind on reg setting after a serries of tests done with revolver unreged,and found i could get the 15/16 fpe i wanted from 14.3gr pellets at 1500 psi, i wanted to run the revolver at 2800/3000psi fill pressures 2800 being my preferred fill pressure to get best used from my 3300psi hpa bottles,after very frustrating week of trying various combinations of bellvill washers in reg i finally got it set to 1500 psi and after bit tinkering with reg piston opening distances got the revolver running sweetas at 700fps with 14.3gr pellets for 15.5fpe and 650fps with 18.13gr pellets for 17fpe,exactly where i wanted,reg running just fine with only 1/2fps variation per shot over 14 shot string at 2800psi fill pressures,learnt good lesson here ,never take anything you are told as being true eh,but all turned out excellent in the end and now having lot fun with the pcp revolver,but as some will know its been long time getting these handmade pcp revolver to this stage,6 years on and off in fact now,so next time you up here Paul you can actually shoot the thing mate.

At least good to hear you got it sorted. I guess the reg adjuster did not cover the range you needed without re-stacking the washers. That's a great consistent fps your getting.
