I would recommend looking around for an used Kimber bolt action. You'll be able to shop around and get 1 inside of upper end of your budget. CZ rifles are proving to be excellent in accuracy, and feature the only single set trigger factory on any rimfire. Short of that, go with Remington 547, Savage, or Marlin bolt actions. If ammo price isn't an concern, and you just want to plink/target shoot-look close at .17hmr/.17mach2.
