My suggestion would be towards the 358. I believe it will lose less from the short barrel than the '06 based rounds, and you can load some heavy bullets that will penetrate any bear. Good selection of bullets around for the 35 cal too. Short cartridge equals faster reloading for second shot.

It's not a Savage, but you might luck into a 356 Win lever action. Now you're talking fast and handy, like my 375 Win.
