I remember my first bow kill, more than 30 years ago. I used a takedown recurve to shoot a medium sized black bear. As it ran off I still remember seeing the arrow hanging from it's side and thinking that I had gotten no penetration. Then I realized that the arrow was caught by the fetching and hanging off the opposite side. So there I was, on a backpack hunt by myself, no gun. The bear piled up a short distance away but resting off the ground on some brush. Was it dead or not? Pretty exciting stuff at the time.
A brown bear with a bow? No thanks!
