I like them both, but I chose the 7mm-08. In Kentucky, my state of residence, they have a minimum .277 caliber requirement for elk. Although I believe that with good shot placement, the 6.5 would do the job, it would not be legal in my state in the event I get drawn for the elusive Kentucky elk tag.
Some game regs are simply dumb. A 7mm-08 is good to go, but a 6.5-300 Weatherby is inadequate by rule.
