Airforce CONDOR, 24" bbl, home made schroud & moderator, drilled and tapped a very small Allen screw which allows adjustable hair trigger, pulled the valve out and chucked it in my lathe and tapered it and other mods to eliminate it from being the valve being sucked closed giving you a weak shot on a full bottle. (Or I coud have just filled it to the top of the sweet spot.)
Loves predators- 940fps, pests hate them.
Invasive species doves- took 30 of them a couple summers ago 30-92 yds, 90% 65-75 yds.
Eun jeun/ SENECA 28gr out @ 1005 fps.
(I did all these mods my ideas,, before available 20 yrs ago.)
*Dennis Quackenbush (THE GRAND FATHER of Hi power air rifles!! IMHO,
357 pistol, no internal mods, just a 2nd bbl- 32" & 9.mm. 40 gr pellet! 930fps and a Crossman skeletal pistol over grip rifle stock. Modded to be the Lightest ride ever made! Perfect for coyotes! Wont get 5 shots anyway on a yote, so its perfect.
