10/22 is my pick....
I have one that is outfitted with a integraly suppressed barrel and a competition McMillan stock. Accurate as hell and quiet with the exception of the sonic crack. Glass is a Weaver "Grandslam" target dot. Needless to say, rodent population drasticly decreases inside 100 yard radius of the compound.
Even before the "stock" barrel was replaced, it would shoot ragged one hole groups that could be covered with a quarter at 50 yards. (It was the "bull" type hammer forged) The weapon was relatively short but as far as I know,I am not aware of a 10/22 that is easy to "take down".
Only thing more accurate would be some of the higher end bolt guns like the Kimber.
