Are you planning a Black Bear hunt this year or in the future?
Don't wait until you are in camp to study Bear Anatomy and shot placement. Here is a chart and information on both. See my post on selecting a cartridge and bullet for black bear hunting over bait for additional information. Here is a website link where you can view cross section photos of a bear's anatomy.
