Can somebody give me a general idea how to increase the shot count on a regulated Marauder? I currently get 75 shots. I want to get more if possible with Crosman Premier 10.5 grain pellets at 875 fps average.

I do not want to touch the regulator. It is set at 1500 psi. I want to leave it alone.

What should I do with the hammer spring and the transfer port screw adjustments to increase the shot count?

Hi Leo,

I'm assuming you are getting 75 shots on the reg at 875 FPS currently and would like to improve  efficiency of air consumption. You are right at 1 FPE / Cu inch.

You can try closing transfer port size(clockwise) and increase hammer throw (1/8 allen key counter clockwise) or increase / decrease spring pre-load (3/16 allen key clock wise increases)

You can also improve efficiency with after market hammer de-bounce kit, twin spring system guide or SSG. I've seen people reporting efficiency as high as 1.7 FPE / Cu inch with those devices.
