I am waiting on a 6.5x284, but this might be a little more than you need. For a lightweight rig with easy recoil, I would look into a .260 Rem. I recently shot a 7mm-08... what a sweetheart of a caliber. It was so nice compared to the .300s up to .416s I am used to shooting. Actually, it was a big reason for me "stepping down" to a 6.5x284 for deer sized animals. The .260 will give you more reach than the 7mm because of better bc bullets. Actually, just the range you are looking for. Short action, light recoil, in a lightweight rifle....what's not to like? Writing this, I am wondering if I made the right choice!
