I've found good accuracy from many of the earlier .22LR rifles of almost any make. This 1956 Winchester Model 75 sporter will give phenomenal groups out to 100 yards. Like their big brothers, the Model 75 target rifles, these had the match chamber and twist designed solely for the LR round, and the headspace was carefully calibrated. The bolt was marked with the rifle's serial number. It's the most accurate .22 I own, even though it was manufactured 62 years ago.
Many rave about Winchester's Model 52 sporter, derived from that company's primo target rifle, but I favor the Model 75 sporter, which was much lighter for field use. Ideal for small game.
