What do you think about the risk of running into grizzlies during a sheep hunt? pack more gun? or just let the guide back you up?

I think I'd rather have 2 capable rifles vs. 1 guide backing me up. and the 300wsm is much more capable than a 7mm-08/270wsm I think.

I think if weight was the only factor etc...and sheep only, the7mm-08 would be fine, but the risk of bears makes me think the 300wsm is more correct, but I'm sure there are plenty of sheep rifles out there in the 270win, 7mm-08 type...
