Since about 2016 I have decided on .22 LR CCI Standard Velocity for paper punching and CCI MiniMag for woodswalking in my Ruger MkII ( bought Feb 1987).
For about 30 years I fired whatever I was buying and trying in my .22 rifles: CCI SV, Win T22, Rem GB, CCI MiniMag, CCI Stinger, Aguila 60 gr SSS, Fed 36gr HVHP, Fed Auto Match, etc
After breaking the bolt stop pivot off the bolt stop pin and realizing the recoil spring was weakened enough to eject and reload from the magazine with .22 Short, I ordered and installed new bolt stop and recoil spring assemblies about 2016.
