First, what gun? If it's a Marauder, what does the #5.25 refer to?
If I recall, for Marauders HS is Hammer spring tension, HT is hammer throw, and VST is the velocity screw adjustment. Without knowing each of these values no one can advise you. If that's a Marauder you should be getting either more power or more shots at that fill pressure IMO.
Just for example my .22 Marauder gets 30 good shots on a 2100 psi fill from 730 to 745 and down to 725fps with JSB 18.1s. Check out the Marauder Forum, it'll make your head spin with the possibilities!
