What's your point by this comment?
You just stated exactly what I did in my post...........show the angle of the deer facing straight away. That really gives a better look at the position of the entry and exit than that offset picture.

With the animal facing away you can get a better orientation of the very top of the animal and where the arrow went in and out.

It's definitely a weird one........it almost looks as if to exit where the arrow did the arrow would have to go right through the spine but obviously it didn't. The deer's body is curved, not straight sloped so the broadhead obviously didn't ride right under the skin in an arc coming out where it did or the skin would be gashed wide open.
I still think that some internal organs (most likely intestine) had to be at least clipped. The question is if they were do they heal on their own and at what rate? I wonder how sharp the broadhead was as well.........I can't remember if Rob mentioned it or not but I seem to think he mentioned that his cousin isn't a very "serious" type bowhunter so who knows what condition the blades were in prior as well.

Hopefully rob can watch this buck throughout the season. I'd say if he makes it through the week or so he'll be fine.
He sure is acting it right now. I know if I was hit through my intestines with a Muzzy I'd be lying on the ground screaming and crying like a 6yr old girl who just got her favorite Barbie doll taken away from her.

I had the exact opposite impression of the exit wound than Mauser did too..........very modest and not a lot of apparent damage.
