Several years ago I took this shot on a deer I rattled in. He came in fast and stopped under my tree. He was headed in a direction that would not allow for a shot after passing. The arrow entered beside the spine and did not exit. As the deer ran off I was kicking myself because of all the arrow sticking out. I assumed it had not penetrated far enough. After an hour I tried to trail but there was no blood. Apparently the arrow did its job and cut up the lungs as he ran off and eventually worked its way down thru the brisket. The last 10yds was a stream of blood. Fortunately he didn't go far and I was able to recover him by simply following the general direction he went. If I had it to do over I would not take the shot as at the time I remember how sick I felt thinking I had wounded the animal and would not be able to recover it.
