That's a great buck. I would say your shot is above the spine.
"No Man's Land" does not exist. There is no void below the spine that is above the lungs. Good luck with getting him!

Lot's of misconceptions of thoracic anatomy in this thread. Like another poster, I'm a Registered Respiratory Therapist with over 21 years of clinical experience. Let me settle a few of these. First one has to understand that the lungs will fill up the entire thoracic cavity on both full inspiration and full expiration. The differences in volume is not because the lungs get smaller INSIDE the rib cage, it's because the ribcage's internal volume gets smaller. The diaphragm moves towards the rear of the animal and the ribs swing towards the front, increasing the internal volume of the thorax. The lungs are "pneumatically sealed" into the ribcage. The lungs can seperate from the ribcage only when either air or a fluid is allowed entry into the space between the lung and ribs (pleural space). This will all be true with the animal in any position or orientation.
Whenever you "double lung" a deer you're taking out both lungs hopefully. When you single lung a deer they can live longer bacause they still have some potential respiratory capacity in the undamaged lung. The reason some deer live even double lunged is that the lungs are pretty good at sealing themselves up and consist of several lobes. This means one lobe can be deflated and blood/the arrow/foreign matter can plug the airways between the lobes and allow the remaining part of that to have a least a minimal respiratory capacity."https://www.youtube.com/watch?v=eQ5fkdN0tuI
