Myself, i can't see that the bullet traversed 3/4 animal. The entrance was near the center of the rib cage, and it exited the neck. Seems that would be some less than 1/2 animal.

You're right about the angle. I drew down on the deer, and was waiting for it to turn broadside, or at least quartering away. As i waited, i noticed how steady the cross hair was on that spot just behind the shoulder. After a short time, i grew tired of waiting and took advantage of the, to me, unusually steady hold, and squeezed off the shot. The rifle wouldn't have been more solidly steady, if it would have had an attached bipod, and i have no idea why.?!? Perhaps it was the lack of loose elbow, due to whatever old people disease apply.
