Home Forums Hunting & Shooting Air Guns Air Venturi Avenger, 25 Caliber

Well that's it....I've been assimilated to the Dark Side.

Just got this Avenger up and running. It's a tack driver.

The gun arrived with about 1K psi in the tank. I degassed it, dropped the regulator setting to 1/4 turn ccw from the bottom, refilled with hand pump to 3100 psi. It's rated to 4350 psi/300 bar, but since i'm hand pumping, 3100 seems good.

So after getting it charged I broke out the chrono, and made a minor increase on the regulator, to get velocity from 790 fps at minimum, up to 810 fps. It only took maybe 1/8 of a turn on the reg screw.

So my settings are just a hair over 1600 psi on the reg, and hammer spring all the way out, minimun spring pressure.

Velocity 810 fps with JSB 25.4gr. I shot 28 rounds, and that brought my reservoir pressure from 3100 to 2200. Probably 40 rounds would take the supply down to the regulator pressure, at 3100 fill. I can only guess a fill to 4350 psi max fill, would yield around 80 shots at my reg setting.



25 yard zeroing, sub 1/4" 3-shot groups.


55 yards, sub 1" with the two 'flyers'. Not bad considering breeze 10-14 mph from 7-8 oclock.
