Rob, didn' t mean to sound like I am saying you are wrong. I don' t believe I said that, and if I did, then sorry. Just meant I disagree. When I mentioned hitting something else besides a single lung, I meant hitting something more behind the lung, like a liver, especially at an angle where the deer is walking directly away from you from a stand.

Sure, this is a judgement call tracking shot, and it depends on what a hunter believes in. Personally, from the experts trackers that I have read up on, what I have experienced, and what I have heard from other experiences, I believe, that if I have a pass through single lung only shot, I would get on the deer right away, to keep the blood flowing. If enough blood is lost, you then at least have a chance in recovering the the deer (putting another shot into the deer will probably be required). Chances are that the deer will not bed down anytime soon, will not seek water, and will not feel sick (the natural reaction to a deer feeling sick is bedding down, as experienced by a stomach, intestine, or liver hit).

Many expereinced hunters believe that this is one of the toughest shot recoveries on a deer. It will be tougher to recover this hit then a stomach/intestine hit. Now none of us (I hope) would ever try to hit a deer in the stomach or intestines, so my only advice that I would give would be that if you are not sure that you can take out both lungs, do not shoot.
