New Valve latest test!!!!
I FIRED 3 SHOTS FROM A 220 BAR FILL:
28 GRAIN EUNJIN 996 FPS 61.7 FPE !!!!
17 GRAIN PREDATOR 1140 FPS
21 GRAIN KODIAK 1050 FPS
BECAUSE I GET GOOD NUMBERS LIKE THIS WITH AN OVERFILL, I KNOW I CAN OPEN UP THE ORFICE A LITTLE MORE. THIS MEANS AT LEAST ONE MORE POWER INCREASE IS AVAILABLE!!!
DOSNT AIRFORCE ADVERTISE CONDOR AT 60 FPE?? AND THATS WITH A 24 INCH BARREL
I AM USING AN 18 INCH BARREL AND STOCK TSS SPRING AND HAMMER
MORE TESTS TO COME….

AF advetised as the most powerfull rifle airrifle in the world….just a shame that the career 707 mk2 has been spitting lead at 80 fpe for years
cant wait to see what your valve will do with a longer barrel.
i had my valve and a 23″ .25 barrel + 42 grain EJ hit 107 fpe, with a 230 bar fill, of course spring and hammer where modded as well, unfortunatly in my experience the 42 grain is not that good over 900 fps….but it shure went bang !
im sorry i cant give you any info on an 18″ barrel….best i have done with a 12″ .22 is just shy of 50 fpe on a tweaked condor valve and EJ
with a tweaked talon valve + 12″ it does 32 with crowmagnums, and 36 with EJ in .22
