Could be your extractor is out of spec. Remove bolt set round on bolt face with extractor holding round if casing falls out you need a tune up or new extractor, head space should be around .41 don't try to change this your self. but an out of spec. head space can also cause stove pipes. If extractor holds round try taking it out of bolt and polishing. My main 10/22 has tens of thousands of rounds through it and about the only parts that I have not replaced are the bolt and the extractor. I have fixed a lot 10/22s by head spacing and extractor reshape or replace. also as the other posters note a super good cleaning could fix your problems. Tight chambers, uncomon to this gun, will cause stove piping, unless you have the target model. they use a tighter chamber. Last of all some of the Ruger magazines are just no good.
