Something that some "bear killers" don't know is that a bullet put into the actual heart of a bear will not stop him. A bear's heart rate is slow, slow, slow giving him time to kill you even after you putting a bullet or several into him. A CNS shot is all that will prevent him from killing you. Lots of luck with that when he is charging you!!!!
Of course what you say about a bear having a slow heart beat is true. But when you say that a CNS shot us the only way to keep the bear from killing you, is most certainly not true. Too many instances where body shot saved the day.
