I have a friend who got lost and spent the night in the woods. When he woke up he stood up to take a leak. When he did a bull stood up about fifty yards away. He dropped it with one .30-06 cup and core through the front of the chest. It got up and presented the same angle as before so he shot again. With the second shot about a dozen got up and ran off.
To his chagrin he discovered he killed two. A four by five and a five by five. He found a near by camp and after a few minutes found out the guy was delighted to tag one. He took my friend's around the mountain to his camp. He was so distraught he never hunted again.
