Okay here it goes. I currently run a ULT xvalve and it runs perfect with 7 shims. I decided that i was going to use the stock on.off and i gave it a very good lubing. The on/off looked perfectly fine with only about 1 case through it. Well i dry fired the gun and it was bouncing like crazy :). But once i put balls in the first shot would go off and the second would vent like crazy. The bolt would not reset and if i tried to pull the trigger nothing would happen. The vent would just continue.I checked the input gauge which was about 1000psi input and it was fluctuating all over the place. Turned off the tank and noticed that the valve wasnt even storing the 400psi it usually does. I went through about 1700psi in my tank with 3 shots. It was venting pretty bad down the barrel. Iam running the 2.5 carrier and no shims with the red spring with the velocity set at around 280-290

my best guess is that somethin isnt sealing. Id check all the orings on the on/off and oil it all up. if that doesnt work id ask someone like blackvcg and go through the ult threads in detail.
