Thats and easy one...Win. Mod 63 auto, they all shoot tiny groups and they are the best 22 ever made...in a bolt gun I would opt for eithe one to the old Brnos or perhaps the Win Mod 52, they both shoot very well indeed. these are not cheap guns but they are the best of the best..I also like the Marlin 39 Lever guns, but that wasn't your question.
