sweeet, im gettign one as well and its really humid here in Saint Lucia that does affect FPS and also 600mm barrel. im just trying to get to know more about them, your factory hammer settings you said does well with the reg set at 130 bar? thats pretty great, i know each os a bit different but ill try the 130 bar if mine isnt there when it arrives as i mainly wanna shoot the hybrid slugs from FX at 40ft/lb
