I recently purchased and ended up selling a 10/22. The best "group" I got with it was about three inches------at twenty five yards. Average was about four inches. Very poor rifle. I tried every adjustment anyone suggested to get it going except replacing the barrel.
I really like the old bolt action rifles. I still have the first one I ever owned. It isn't a target grade rifle but it will still take squirrels consistently out to 50 yards. 95% of my squirrel shots come at less than 20 yards. Usually, I am almost under the tree the squirrel is in. I seldom get to try long shots anyway.
I am also seriously impressed with OS OK's shooting abilities. He is far more capable with iron sights than I am. The only way I can come close to him is with a scope.
