Must of missed the brain or the bear was just reacting from the brain hit.
I performed a “field necropsy” on the bear. My first shot(a Nosler 150gr. tipped soft point) hit him just under the right eye, blew out the back of the skull, traveled along the spine, and I recovered the 30 gr. base of the bullet between the hide and the ribs on the right side. It had penetrated about 24”. I believe that was a kill shot but the adrenaline dump was so strong he just kept on coming. The fourth shot tumbled and made an elliptical entry wound at the left chest, traversed across the ribs, and created a 6” diameter exit wound that completely tore the right foreleg away from the shoulder. It was pretty dramatic. Best part is I lived to tell about it!
