Hi all i have one of the early model fx crowns in .30 cal which was originally a .22 but swapped barrels this has been sat in my cabinet for over a year now and its getting tatty so i want to spice it up abit and get some tuning parts made .
well as standard she shoots 44gr jsb pellets maxed out at 880fps and thats with reg at 165 so i was hoping somehow to lower reg but still get that speed or even tweek it to get upto 900-920 ,
my thoughts are hammer weight but not sure how heavy , valve seat was told by ernest should be 6.5mm is this correct and was maybe goin to machine a pin probe and port the barrel please give me your thoughts on what to do thanks steven
