There are so many options on sub MOA rifles out there anymore. Im very partial to Savage rifles, any of the 10-12-16 rifles will perform well under MOA once you find the proper food for it. Of course optics quality are just as important as the rifle itself. The midrange Athlon Optics scopes will fit into your price range with a new savage and will last you a very very long time. As far as my choice of factory ammo (I roll my own) id stick to BHG or Federal Gold Medal Match with 168 grain Sierra Gamekings.
Happy shooting!
