Assuming you hand load (and like it) 280AI would cover a lot of bases. I'd think a Montana would be pretty sharp in the recoil department. I hated my 270WSM Montana.

Handloading for me anymore is like watching paint dry, which is why I'd take a 270 over 280AI these days. Sure, you can load "for half price" or better.

All a matter of how much time you have on your hands.
