I had the same results on black bear TOW2ATM. Two shots, two hits, basically they made an x through the chest, behind right shoulder and throught left leg, hitting bone and then through right shoulder and out low behind the left. Bear ran 500 yards before dropping, and was standing still at the first shot. In my opinion there is no way the bear should not have dropped on the first shot. That was the last time I used them. They get great penetration but did not expand nor transfer the energy into the animal. Not worth my money in my opinion.
