Bears are bears. They all want the gut pile first. So move it or your meat well away from each other. That will buy you considerable time since the bear will bury the gut pile and come back some day down the road. If you take a gun and shoot a grizzly, understand that the feds will try to persecute you worse then if you had killed a human. I live in grizzly country and guide elk and dear hunters for aliving. and I choose to carry nothing. I have tested spray and it works. I used to be very skeptical of it that's why I tested it for myself. I have a better chance of climbing a tree then trying to shoot a charging bear in close range with any success.
