Just happened to stumble on some reviews on You Tube where it appears that at least some SR 22's and Winchester Super X are not a good mix as the jams are about every shot. What is even a bigger puzzel is that they show the same SR 22 working flawless with Remington Golden Bullet & Remington Thunder Bolt. I also noticed that in the Cabela's reviews of .22 ammo the Winchester Super X is taking a beating on there also. Last Winchester .22 I have shot was from a bolt action rifle and that was before the great .22 ammo shortage. Guess my question is not if anyone is having issues with SR 22 jams but what's up with Winchester .22 ammo?
