Reply To: So how are those FX Crown's doing so far ?
My Reg pressure is set at 130 on gauge, I also adjusted hammer screw accordingly, just remember that increasing just the regulator pressure will drop the FPS, remove your bottle,
shoot once to degass, then use 2.5mm ball end hex key and turn screw in maybe 1/2 turn, screw bottle back on and turn reg screw CCW keeping eye on gauge, when you get to say 120 bar shoot gun once to stabilize reg pressure. then slowly increase until you reach 130 bar. I set wheel to #4 and checked FPS with 25.4’s. Then adjusted hammer tension
to get where I wanted to be (885-890). Then I increased tension to MAX setting and shot 34 gr JSB’s and they were right at 840 – 845 and that is where I stopped.
If you shoot 25.’s on MAX they are too fast (940) and groups open up. The 25.4’s like to stay under 900 fps, the 885-890 speed are really accurate.
