umm I'm not sure on exact figures but at 110psi with a decent potato at least 200m. I can't see it leave the barrel and can only just see it at about 50 m out. I'm using my video cam for the pics, its a jvc everio gzm 505
Yeh the barrel knife wasn't measured exactly

I just started cutting with a hack saw. Its bevelled so its actually sharp, I rammed a massive potato too hard and gouged a chunk of skin out of my knuckle on it
The problem with the valve, pvc, was with they way I was filling it(not enough air flow to seal it). I fixed that problem by getting myself a big air compressor.
@ JSR: perhaps I should have painted it periwinkle blue?
Always out numbered....
never out gunned
