Looks as if the deer was shot while walking directly at the shooter. There' s several posts about this type of shot and whether to take it or not. This supports my opinion in there being no shot on a head-on or straight-away deer. Not every deer is going to survive with a broadhead through one of his lungs, but it goes to show you - this is not a good shot to take. If the deer hadn' t of survived, it would have gone a considerble distance anyway.
