So I really wanted to get the maximum power out of my puncher breaker, I sent it to Troy a year ago and I think it came back shooting RD Monsters at about 860 for about 30 shots. I really only need one mag for hunting so I've been tuning it little by little. I took a lot more metal out of the valve; opened up and sloped the valve stem tube and shaved a few hundreths of an inch off the tube so the valve stem could travel farther, turned down the valve stem then changed it out for a stock replacement and modified that one quite a bit (not shown), dremeled out the transfer port on the valve with a steep angle from the inside out and opened up the TP all the way from the valve to the barrel to about .188 and oveled it some, then I bought a longer barrel from a Kral Knight (a few inches longer to 22.8"), it has the dual spring hammer, polished all the contact parts glassy, still need to polish new barrel, opened up the valve tube screw cap on the back of the valve with a steep slope.
Today I took one shot with 170bar in the tank and it shot a RD monster at 1030fps! Psyched as this guns shoots slugs really well. Litterally haven't had time to even take a second shot let alone a shot string or accuracy tests. I'll probably back the HST screw out a few turns and shoot some 24gr slugs at 50FPE for a mag or two, man if I can get 24 shots at a consistent 50FPE.. ugh, that would be a success for me (a hack of a tuner..) More to follow, just wanted to share some excitement.
