Oh, really? Uh huh. Just spent a consecutive 13 weeks among them, after at least four decades of doing the very same thing during the previous 40 springs, or so. But of course, if you think that a .270 Winchester can't handle a coastal Alaska brown bear, that's fine. I won't argue with your choice of heavier caliber. But, I thought we were talking about minimum under ethical fair-chase hunting conditions/situations?
