Finally got some time to find and fix the power loss it turned out to be the valve assembly ''2250-016 Valve Stem'' my fault I had reduced the brass center to much compromising the seals stability, put a standard Valve Stem back in left the other mods and got an increase in air pressure so a happy bunny, will mod the Valve Stem another day and re-crono as I'm always looking for a little bit more, would be nice to have 600+ FPS as an AVERAGE this is using C02.

178.6  182.8  183.5  184.1  182.7  Average 182.34 = 597.836 Feet/second with 14.5 grain pellet that 11.37 Foot-pounds. A spread of 5.5. Not to shabby with a 2240 I think?

Thaks again to all for their thoughts and suggestions.

A case of over-mod.   ;)    None to shabby indeed!!!   :-* :-* :-*

That's pretty healthy for a 7" barrel. Nice work.

Have to agree, that's some excellent numbers for a 2240 OEM barrel.

I've never wanted something so useless in my life.
