My most finicky .22 is my M41. It hates Remington but since I've switched to CCI standard velocity 40 gr. ammo (many many years ago) I honestly don't remember having a single jam or malfunction. I did have one or two bad primers where the round failed to fire (even after multiple hits) - but that was a defective round - not a gun/ammo issue. IMHO the rating of .22 RF ammo is the following (best to worst). Again, just my opinion & experience ......

1) CCI
2) Federal
3) Winchester
4) Remington
