Careful what you wish for... I live in Alaska and have shot or been on over two dozen bear kills. Very few of them we were actually hunting bears. I have been within 10 yards of brown bear cubs on too many occasions. I use a Remington 700 300 UM, 200 grain swift A frames when in bear country otherwise I use 145's. My firearm has a 4.5x14 VX3 30mm but have had to aim down the barrel twice. The last time I was charged by a huge griz and had to shot him in the head at 10 yards otherwise I might not have had time for another shot.
Here are a couple of my bear videos.
Enjoy!
