OP, at reasonable ranges, there is no appreciable difference in a .270 and 308, as far as performance on game, when both are loaded with good bullets. I've used both extensively. I am a little bit partial to the 270 win. It was my first CF rifle cartridge and I have killed enough game to fill a couple of large dump trucks with it. Lately, I've been carrying a Kimber Montana in 308 @ ~6 lbs, all-up. Hiking steep and far certainly favors that rifle. It kills chit.
Bottom line is that the bullet shoved in the brass matters more than what is written on the base of that brass.
PB, that could be said about any number of cartridges. Like the previous noted calibers, it's an option for the OP that deserves mention. Seems most people, including yourself, have or had a favorite. I agree that it's the bullet that does the job.
