I would get a Ruger 77 Mk II. They are about $450 at walmart and they come with rings and have the intrical bases (one of the best systems out there). You will most likely need a trigger job but it will still total farless than $750. Ruger makes a great gun and in my experience with mine and my friends they are all very accurate 1" or less at 100 yards.
