Brown bear sow with very young cubs. She's aware of your presence, agitated and 35 yards away.
What's your poison, 7mm RM running 160s at any velocity or .338 Federal running 210s?
Neither. I own and shoot both, but I'd take something like my Ruger .338 RCM over either of these choices, especially when prowling around thick stuff.
If you're fixin' to put a hole in something, make it a hole to remember.
