A whitetail that is double lunged will go as far as 60 yards or so. He will usually travel down hill if he/she can and generally leave a nice pink blood trail. I also understand they get very thirsty very fast so down hill to water if the blood trail can't be found. Since there is not much in the pleural cavity you can usually expect a pass-thru of about the same size as the entrance hole.
