I did some more testing with Stubby and the R&L Airgun Supply "Extreme" valve in case anyone is interested. With the Airforce airguns you can mix and match nearly anything. I am waiting for a 30 cal barrel to test with the Extreme Valve (in my Condor) but here are some numbers with the 22 cal 12" and 24" (in Condor w/ Extreme Valve) barrels and 25 cal 12" barrels. All are 10 shot averages - 2900 psi fill. Realistically the Extreme valve is good for about 20 powerful accurate shots on the tank before velocity starts to fall off significantly and maybe 10-15 more shots for plinking. If I can get 10-15 shots from the 30 cal barrel above 150 fpe I will be real happy (similar to the new Rogue).Stubby 12" 22 cal barrel Extreme ValveEun Jin 32.4 gr801 fps 46 fpeKodiak 21.14 gr943 fps 42 fpeBenj Disc. 14.31044 fps 35 fpeStubby 12" 25 cal barrel Extreme ValveKodiaks 31.02 gr884 fps 54 fpeJSB 25.4 gr937 fps 50 fpeCondor 24" 22 cal barrel Extreme ValveEun Jin 32.4 gr1001 fps 72 fpeKodiak 21.14 gr1172 fps 64 fpeBenj Disc. 14.31275 fps 52 fpe

I extrapolated from other testing that the 24" 25 cal barrel on the Condor with 43 gr Eun Jins will do 80+ fpe. Opposum power.

From my testing it turns out with the Extreme valve and Kodiaks and a 3000 psi fill the shot string is nearly identical to the TalonTunes Shorty 25 which is basically the same thing minus the Stubby stock except it is $1100. The Stubby Extreme for $856 gets the stock too. I am not sure I would want Stubby w/o that fabulous stock.
