Did some research, and read somewhere that 30-06 would the minimum sized bear gun. 308 is a little on the light side, but I'm (almost) sure it would do the job.


Inside 50 yds, you can fill him full of lead (ie you'd be lucky to get two shots off with a bolt action rifle), but will you be able to stop him in time? Blood can continue circulate long enough in a bear to do some damage. I would think bear spray should be effective, but if a bear is charging at me it's gonna be the rifle.
