I gotta say I was always a fan of the 260rem, absolutely love the 6 5x55 too, I actually love the Creedmoor to but not so much as a long range killer but as a modern and very accurate reinventing of those too.
It's got very mild recoil and will kill any deer at the same ranges as the older two.
But the 6.5/284 and 6.5/06 are still the best 6.5"s for longer range hunting, add the new 6.5wby nag and the same if they a 6.5PRC yet.
