Any broadhead suitable for whitetail are suitable for black bear. Remember, black bears hides are thinner than that of a whitetail although their hair is thicker. Shot placement is the key for both. Study the anatomy of a black bear and make sure of your shots. I took my black bear with a 100 grain Muzzy 3blade, it passthrough'd the length of the bear from front to back and split the femur in half on the way out. It was the way he was standing and I took out the top of the heart, lung, liver and exited the rear leg.
