RE: Caliber Choice
For deer & bear (excluding Alaskan Browns), the 270Win., 280Rem., 308Win. or 30-06 will do just fine. Magnums not really needed, but if you must have a belt on your case then look to the 7mmRem.Mag. If you feel you want bigger than that, then skip the in-between stuff, and go for a 338Win.Mag. - with it you would have something suitable even for Alaska.
