Quite the video!
I was waiting to see one of two results:
1. Hunter turns rodeo “bulldogger”, grabbing the deer by the horns and wrestling it to the ground, perhaps finishing up by lashing three of its legs together as in calf roping.
2. The deer inadvertently (deliberately? ) hooks an antler tip into the trigger guard on the rifle, er … shotgun, turning this into a “deer shoots hunter” story.
