This is typically a problem with some 10/22's the firing pin is just long enough (in some) to touch the barrel. It peens the mouth of the chamber a little causing extraction problems and eventually feeding problems. One quick way to check it is to lightly oil some rounds and shoot them. If they all feed it is either a rough chamber or most likely a burr from the firing pin hitting the side of the chamber mouth.

Our club has regular 22 tactical shoots in which most use 10/22's. our of 5 with this problem 4 had peened edges of the chamber.

Most times you really can't see the peened edge as it is just slight. But when you put in a gage pin, you can feel the resistance.

Just a personal observation from a 10/22 junkie.
