2 friends and I did a drop-camp Caribou hunt on the N slope of AK in 2011. 2 270's shooting 140gn Barnes TSX and 1 7Rem Mag loaded with 160gn Partitions. We didn't even see a bear, but, I guess I wouldn't have felt undergunned with the 270's or 7Rem we had in camp. When we got back to Kavik we found out that a camp 5Mi up-river from us had to DLP a Griz that wouldn't leave their camp alone.
In a "hunt" situation, really about any rifle I could shoot well with a fairly stout bullet would be fine.
In a charge/wounded/pissed-off bear situation I'd want every ounce of kenetic energy and every MM of penetration I was capable of summoning.
I can walk on water.......................but I do stagger a bit on alcohol.
