Bob, I understand what you are saying and I have pushed a deer to it' s end but it was an artery shot in the rump that my cousin made, we kept jumping the deer until it was exhausted......pushing a single lung hit could go either way....it' s a tough call and if you are experienced enough at it and know your property, by all means that may be what' s in order, however...they can travel great distances when pushed and if you don' t have those resources...the animal is gone. I guess it has to be up to the individual. If other organs are hit though, like Wimp mentioned above, waiting might be the key.
