I've got a Ruger 10/22 that I've had since the late 70's when I was doing coons for a living, mine was always surprisingly accurate but in later years after a lot of use it's accuracy declined. This prompted me to consult the worlds greatest source of knowledge and as a result of what I was told I removed the bolt and thoroughly cleaned and reassembled it, a new experience for that gun and I. I'm happy to say that it's accuracy has been restored to it's former exceptional status, cheers Google.
