Twizi that was probably one of the most ignorant things I've heard you say. If you look around the form, people get 600+ fps with sprinnkler valves at 90 psi with marbles. His ammo in this case weighs .43 grams which isn't even half of a gram.

Yeah, it's that important.

I missed what type of valve this gun is going to use? The velocity will depend on that too.

Its a sort of blowgun with a trigger system, i have only seen something similar once on spudfiles. The airpressure pushes the piston wich is retained by a trigger .

With a .43 gram projectile at 520 fps i can still dent 1/2 milimeter steel to give it an half bb shape impact. Not bad .
