Reply To: First shot lower fps on regulated pcp
That likely means you are getting a slight bit of regulator creep. If your gun is “tuned” correctly and the reg is set for like 1500psi. If the regulator creeps up a little over time then when it sits for a while it will be at like say 1600psi. If you strike a valve with the hammer tuned for 1500psi, and there is 1600psi in the valve it will not open as far/fast and there will be less air expelled and the shot will be slower.
