Well, no offence intended to anyone, but, if you know many highly experienced "western" Canadian hunters, you will find that many of them TRIED the 6mms and a few the "Bob" and you do not see many of these still using these rounds.
That is, of course, due in some measure to the usual purchase of a few rifles to be used on ALL legal big game species and very few will choose a .243Win. in this role over a .270Win. where the same rifle will be used on both deer and elk.
Like you said here, it is a bit different when you are a resident and moose, elk, deer etc can all be on the menu. When I lived in Manitoba I often took a .250 Savage because the only thing I was hunting was deer. I will be leaving shortly on my annual "big" hunt. I won't be carrying a .250 Savage.
