My current favorite semi-auto .22 is a Ruger K10/22-22, Wal-Mart special, with a 24" GM fluted sporter barrel.
If you want a reliable, but less accurate, rifle, the Remington Nylon 66 would be a good choice. They feed flawlessly and as long as you clean the powder residue off the bolt/barrel interfact every 1,000 or so rounds, as long as there is ammo in the magazine they will feed, fire, and eject.
If you like rifles that feature blued CM and walnut, the old tubular feed Winchester 77s are good rifles. The clip magazine 77 Winchesters that I've owned, shot, or fixed haven't been nearly as reliable as the tube-feed 77s. They are kinda heavy and don't have the best triggers, but they are generally quite accurate.
