Jim said recently with the 500cc bottle and 20" barrel he had it tuned for 900fps with the 44.75gr and from 3200-2200 got 40 shots."Bullfrog"
Most of my gun uses the first production run parts. Even so, I get just under 60 shots at 74 fpe, which is pushing the 44grs in the mid 860s. That’s approximately 30 psi per shot on the 3600psi, 475cc bottle. The new bottles are 500cc and fill to 4500psi. I’m also using a 17 inch barrel as opposed to the new 20 inch barrels. So a new gun with the upgraded should increase both power and efficency."Salticon"
Whats the shot count at 870 fps with 44gr??"Bullfrog"I'd say the Flex for this reason... you're going to get more shots than with the other guns for a given power level which is a plus for plinking. This is due to the combination of the Cobra valve (which has no hammer bounce), the larger air tank that fills to a higher pressure, and the externally adjustable Cobra regulator. You can also add different AR stocks. And you can always change your caliber if you get bored with it and run the gun as weak or as strong as you want up to the low 100s fpe.
