Sad news! When they were from Armalite (USAF MA1 survival rifle, AR7, etc) then Charter Arms ('Explorer' variants added), they were good. What kind of ammo were you running?
Remington 575 Viper 22 Hyper Velocity

There is a good reason that ALL target grade .22 rimfire ammo is sub-sonic.
All the velocity in or out of the world is useless if goes whistling past the target. A tossed rock that hits is far superior!
Buy a selection of sub-sonic ammo (under @ 1,100 FPS) and allow the gun to tell you what it likes. From endless rimfires experimentation I can state with some conviction that the CCI MiniMag hi-vel round is the most likely to shoot well, but it will NEVER be mistaken for Target grade!
One of the cheap bulk-pak ammos that has worked pretty darn well in a lot of guns I've ran it thru---both in function AND accuracy is Federal AutoMatch. And a few have detested it. :-\

But you got a few starting places. OF
PS: Vipers are STILL the worst accuracy I've EVER experienced! Any rifle is only as good as what you feed it!
