Rattle-M-Up:
Looks like you are in for some fun. The buck will die, did you give him plenty of time before you got outa your treestand? The tracking job you will have is going to be very difficult, you will not find much blood or any blood at all, look for turned over leaves and stomache matter. The deer will die probably in its bed. I have gutshot two deer, and I have both found them in their beds between 100-200 yards from where I originally shot them. The main thing is to get out there tomorrow morning take your time, and find your buck. It will be dead somewhere you just have to find it.
