I got an old Winchester 290 Semi-auto .22lr from my father in-law. Doesn't want to feed regardless of what I do. Tightened the barrel nut: no change. Cleaned out all the bits of exploded casing from in the action: nothing. Anyone have any experience with these rifles? All in all it seems like a decent little plinker and I'd like to get it working again. I'm thinking of trying to buy new internal components for it to see if maybe that's the issue. Any help would be appreciated.
