I'm no expert, but isn't a .270 a little light for heavy game? It's a nice flat shooting caliber well past 200 yards, but I'm not sure it has the punch for a clean (responsible) kill in elk let alone bear. My 2c, and like I say, I'm not an expert on the subject, I'm just going on what I've been told.
For heavy game perhaps. Not something I'd want to use for a grizzly but quite sufficient for a black. The rifle was a hand-me-down used mostly for deer hunting. Gord was a bit nervous which is why he added the second shot to the head after it dropped and was still twitching.
