In the past 2-3 years 4 guys in deer camp have moved to 6.5 cm or 260. If your not packing in a long way you may want to think about a fcns, fcss or 10 predator Hunter. Composite stocks, aluminum bedded and a little heavier to absorb even more recoil.
You may want to pm popeshawnpaul he used a lw 6.5x284 on a dall sheep hunt.
