All I know is all I ever carried in brown bear country was a 30/06 stuffed with 200gr Partitions. Of course that was prior to the internet, so I was obviously less informed...
Never felt bad about lugging a 30/06 in Kodiak or SE. I've been in on a brown bear killing on the C in ABC and he died without any fuss. Friend was using a 30/06 too.
