Winchester you nailed it. I think it is probably a little that a little break in by 10/22 was finicky at first now it's an ammo pig (eats anything)DrumJunkie said:What ammo are you using that is getting the jams? I had problems with mine (when stock) with Remington and some Winchester bulk stuff. I have run literally thousands of rounds of Federal bulk and had next to no issues. 22's are a little weird when it comes to ammo. It seems no two are the same in what they like, It's a pretty good idea to get a few different types and see what it likes to eat.
