MRV, based on those numbers and my personal testing your regulator is most likely set at 110. There is a common misconception regarding regulator settings. A higher regulator setting does not always increase muzzle velocity. Other factors also must be considered. The relationship of pressure keeping the valve closed and valve dwell time cannot be overlooked. Is the hammer heavy enough (or does the combination of HST and hammer weight provide enough force) to open the valve long enough to provide the proper volume of pressurized to send the pellet at the desired speed? In this case with the Leshiy decreasing the regulator from 130 to 110 bar increased the velocity of the kings from 630 FPS (130 BAR) to 775-780 (110 BAR) with no adjustment of the HST.
my gun is probably 130 bar because speed is .25 jsb (25.39gr) run 777 fps. and jsb heavy (33,95gr) 705 fps.
.22cal pellets speed is jsb 15.89gr 882fps and 18.13gr 831fps. both calibers speeds have been shot 250mm barrels.
Correct me if I’m wrong but that must have also increased air consumption in the end?
