I have a primitive cabin boardering a wilderness area in Montana. A black bear has been eating my bird seed. I moved my trail cam to the cabin and have good pictures of him stealing my bird seed. I am thinking about getting a license and doing a little bear hunt. I would be sitting on my porch with my TC Hawken. .50 or .54 cal. I have both. Shot would be about 15 feet. I know to shoot the shoulder if the bear is profiled, but where if the bear is standing on his rear legs facing me eating from a feeder. Any advice?
