In the end, I don't really think it is "Will the PH save your life" as much as it is "What level of risk are you willing to accept". While hunting in brown or grizzly bear country up here, sometimes I carry a rifle capable of stopping a brown bear, and sometimes I don't. I usually hunt alone, or at least while hunting I am alone. No backup if a bear does charge. My 7x57 is differently not a bear stopper, nor would I consider a 300 a bear stopper. I do try to use common sense and avoid circumstances that would put me in a better chance of bumping into a brownie at zero visibility than not.

What happened to Bob Fontana can be second guessed or claimed if he had more time and a more suitable rifle type scenerio discussion till the end of time, but as it remains, he didn't have time regardless of what he was carrying and it was a terrible unfortunate tragedy that took him away from us.

You can still be a man and not carry the heavy artillery on all occasions.
