Not trying to argue, but for the life of me I can't figure out the hype around the 6.5 creedmoor, especially when it comes to hunting.
Below are the ballistics chart for the most common hunting sizes for the 6.5 creedmoor (143 grain) and the .270 (145 grain.)

.270

Out to 500 yards the .270 has significantly more velocity and energy (knockdown/killing power), while maintaining a flatter trajectory... 30.6" of drop vs 35.4" at 500 yards. The creedmoor does have less wind drift (in the ballistics above there was a 10 mph right angle crosswind) at 500 yards (13" for the creedmoor vs 13.6" for the .270) but it's negligible. The only real advantage for the creedmoor is recoil at 15 lbs vs 20 lbs. (If you duck hunt with a 12 gauge shooting 3" shells that has over 50lbs if recoil.)
Honestly, if you don't like a .270 for deer hunting because it doesn't have enough stopping power, then you are going to hate the creedmoor because it has less in every scenario.
Here's the Ron Spomer article comparing the two...
