For this you don't need a clumsy 26" barrel.

First thing that comes to mind is a Rem 700 stainless SPS, they are not very heavy. Next thing you will need is a Timney trigger for it. A Zeiss Conquest or Leupold VX3 scope and some good quality two piece scope mounts, a sling and case and you should still be within your budget.
