Well...I shot one. I have a lot of white hair and very little blood at the place he was shot, but the arrow shows that is was a pass thru. I tracked small drops of blood for about 50 yds and decided to back out and track in the am. On the way out, 100 yds, I decided to check a couple trails that crossed a nearby creek and found a good looking blood trail. The question is how high the arrow entered.. Wish me luck, sleep won't come easy tonight.
