I initially started increasing regulator outlet pressure to get more ft/s change with the Power Wheel. I was trying to see if I could shoot 177 Heavy, MRD, and Beast without having to change out the hammer spring…I even made a 3.1 mm shim for the LP HS to give it a little more…but even at 190 bar its too much of a pellet weight spread …so now I am back to 140 Reg.
When you did your tests, did you change the PW to see what the ft/s change was between PW settings at those reg pressures? I think you will find that it decreases with decreasing reg pressure.
