If you just want an accurate semi out of the box its gonna be a Marlin mod 60. If you want an accurate tack driver get the CZ 452 or the Ruger 77/22 MK II V-Bolt, not the screw in barrel.
Out of the box, the Marlin 60 is the best buy out there, and they do shoot VERY good. If you want to customize your 22 and make it shoot, get a 10/22.
