I shot one while bear hunting in PA 8 years ago that was hit broadside through the vitals including the heart with a 30-06 165 grain sierra gameking at 10 yards. I thought I missed it because it just ran off, no blood trail or any sign of a hit. Later that evening a friend was about 100 yards out walking toward me, he radios me that he is following a blood trail heading in my direction. He came through the laurel right where the coyote disappeared, we followed the trail back the way he came until the trail went down over the mountain where the coyote laid. The coyote weighed 52 pounds and traveled around 200 yards after it was hit in the heart and lungs by a 30 cal projectile at 10 yards. The coyote went about 75 yards before the blood trail started, if my hunting buddy wouldn't have happened upon the trail I would have assumed I missed because I couldn't find any sign of a hit.
In this picture I weighed 330lbs, and I am 6 ft tall and the dog near the bottom of the photo weighed 55 lbs. just trying to give some scale to the coyote.
