New guy to here! Got a maverick a couple weeks ago 600mm barrel, installed a 700cc tank and slug kit. I'm only getting around 48-50 shots from 250 fill to 150 bar seems really low with the 700cc tank. First reg is 155 and second is 130 power wheel is on 7. I'm shooting the fx 34 grain pellets at 935. any help would be greatly appreciated!!
