Kimber Hunters weigh sub 6 pounds bare rifle and are reasonably priced. 6.5 cm or 308 winny are probably the most practical due to factory ammo availability. Performance between the 3(6.5cm, 7mm08, 308) would all be negligible for what you're hunting. 6.5 PRC might have some "cool factor" and will pack more punch, but ammo availability could be an issue. Personally I'd roll with a 7 PRC over the 6.5 PRC if choosing between the two, based on ballistics. But thats even newer and ammo availability is even more of an issue.
