I'm in the same boat as far as the .270 goes, my step-dad has killed a few dozen elk with his. I've seen him probably take 30-40 different deer/antelope with it as well.
Just doesn't do anything for me and truth be told I could care less if the .280ai isn't a 7mm Rem Mag. I've got one of those, if I want one.
For 99% of my hunting my 7mm-08 will do just fine, I've just always wanted a .280 for some reason and now I'll have a .280ai
