Personally I would keep your eye open for a gun you like and that fits you. Don't worry too much about caliber. As long as its .243 or bigger your good to go.

or set up close and shoot a shoot a slug from a smooth bore if thats all you have. Bears go down easy. Just keep in the lower 2/3rds of the boiler room.
They are there to eat the bait not you, no need to send them into orbit, just kill it.
