How much fpe will a .177 disco do out of the box from a full tank? .22? How many full power shots will you get out of it before the fps drops off?

..Shoots 905 FPS average on first 10 shot string at 29 FPE using 16 GR AA domes (JSB's) and 889 FPS average for next 15 shots and drops off after that to 796 FPS AVG for a composite average of 863 FPS for 30 shots... .....don't know about stock factory .177's or .22's...

I ran a few rounds over my chronograph last night with my Mac1 prepped .22 caliber Disco.
I did not have much time so I put fifteen rounds of each, of the different pellets through it.

JSB Diablo Exact Jumbo 15.9 gr.

15 shot avg vel = 854 fps

energy = 25.59 ft / lb

hi = 863 fps
lo = 840 fps

es = 23 fps



CPH 14.3 gr

15 shot avg vel = 888 fps

energy = 25 ft / lb

hi = 900 fps
lo = 872 fps

es = 28 fps




Beeman Kodiak 21.0 gr.

15 shot avg vel = 750 fps

energy = 26.24 ft / lb

hi = 764 fps
lo = 739 fps

es = 25 fps

Will do further testing when I get time.
