Received my Panthera 500 mm set up 25.4 22 cal redesigns at 950 fps from Utah airguns. It is set to 130 bar reg pressure, macro 23 micro 2.5. Hi 958 lo 935 ad 944 spread 23
Std 7.4 for 18 shots . 250 bar fill down to 165 bar. Dropped macro to 21 and micro to 2.3. Hi 953 lo 937 av still 944 spread 16 std 6.8 . Tank at 170 bar. Going to continue to turn macro down until I can get two mags...

That was what Utah airguns had it set to. Dropped the macro down to 17 micro to 2.1 . Hi of 942 lo of 928 average of 937 fps. Spread dropped to 14 fps and std is now 3.9. With 36 shots and 135bar still in the tank. Higher or lower on macro makes it worse. I am going to shoot this for accuracy to see what it does. I would rather leave it set at 130 bar on the reg..I dropped the macro to 9 micro to1.6 shooting 18.13 . I can easily get three mags 54 shots between 939 to 909with spread getting closer every time I shoot the rifle.
