I concur with what Sambo3006 and no offense taken. I mentioned the SMK due to the fact that's what would be in the rifle for the elk shot. And I'm not level headed enough to carry two different loads and have the right one in the chamber at the right time.
Also note that I'm not ever gonna look for a shot at a grizzly.
Seeing as how Ian opened the opportunity, if I were going for a "big" bear I'd carry nothing less than a 375 H&H with a 300 gr Winchester Silver tip. Even better would be a 375 RUM that way if I had to shoot hopefully the distance could be greater.
The 416 give me the vapors!
