Okay,
With a bear facing you like that, where do you shoot it? You can't get a decent shot to the heart/lungs because the head is so huge. I've been told a shot between the eyes / top of the forehead will likely deflect [even from a .44 mag at close range] because the skull is so thick and sloped. I've also been told a shot to the eye isn't a great shot either because there is thick bone that curls over and behind the ocular socket, so it will likely blind the bear, but not kill it [make it real pissed, though].
So, angry bear facing you like the one in the pic, where do you aim [assuming you are able to keep ahold of yourself and actually aim]?
