Home Forums Hunting & Shooting Air Guns 22 Cal Rifle, Spring or Gas Piston Magnum.

I agree, shouldn't be an issue on a new rifle.

I'm not going to 'put it back the way it was', to check for leaks at this point. But the o-ring did not stand proud of the breech, at all, as it was.

I did gain 30 fps, so something happened that put more power on the pellet. I'm guessing that is more air pressure with a tighter seal.
