@huntsd Ok I’m a little late to this thread and I haven’t taken the time to go through the 3 pages of comments. But I have questions.
You had a pass through with no or little blood trail. My question that comes from experience is how high was the entrance and exit hole on the animal?
I’ve had to track many whitetail with were shot high lung that left little blood. Most of these went farther then 50 yard. The ones that died quickly had chest cavities full of blood. I’ve alway figured they can leave a blood trail until they fill up enough to come out. High shots take time.
