what is the max FPS I should expect with a .30 impact shooting 44 grain JSBs? Trying to determine if my Impact is hurt or if it’s ok .right now I am getting around 860 FPS with everything maxed out....is that normal?
"mrdirect"On my Impact with the 50.15 grain JSB's I am only getting 760 FPS, everything on max settings. (also the valve thing above the bottle), already tried the Ernest power wheel screw fix, does not help anything. 760 FPS is my max
