I think the same thing happened to a hunting partner of mine 2 weeks ago. He shot a doe at 15 yards and said he knew he hit her high. The shot was a clean pass through with good blood for maybe 40 yards, then a few more drops, then nothing. We looked high and low and there' s no way if that deer died on our land that we didn' t find it. The direction it ran it would' ve had to get by 2 of us on stand in order to get off our property and we never saw it. I' m 99% sure he hit that hollow spot and she lived.
