It really depends on your motivation and it sounds like you would like a rig that is an extension of your hunting rig that provides some similarity and supports long range hunting skillls and possibly use the rifle for occasional hunting. I had the same desire. My hunting rigs are in 270WSM and 6.5x284. In the off season I shoot informal long rang targets and compete in a several 200-300 yard eggs shoots in hunting/ factory class. Shoot about a thousand, sometimes more rounds that would burn the barrels out on my hunting rigs in no time. For the off season I currently use a Savage LRP in 260 Remington. Stock dimensions, trigger pull, and scope are similar to my hunting rigs. Very accurate out to 1000 yards, great barrel life, utilizes many of my existing components. The barrel and overal weight is a few pounds heavier than my hunting rigs which helps with the considerably higher volume of shots taken during target shooting and dampens recoil. Prior to getting the LRP is used a Remington 308 Mil Spec with equal success. I did do a little hunting with these set ups but really preferred the ballistics of my hunting rigs. If it were serious, formal benchrest shooting, I would go with a 6Br out to 600 yards, or a 6,5x284 out to 1000. There are other good choices as well.
