I have no real complaints with guys using bigger guns for these outsize deer because a lot of folks in Canada and Montana use 300's or 338'etc for their elk an moose,too.
AA has an excellent post above and it's the traveling hunters that make me laugh because they feel such artillery is REQUIRED for these deer.
I have never seen a bit of difference between a 30/06,a 280,and a 270 on any of these animals (or a 7x57 or 7/08 for that matter).The type bullet used seems to be a bigger factor IME.
