It is interesting how they will run sometimes and sometimes drop right there with what seems to be identical shots. I normally try to take out the lungs because, as a previous poster said, they will die, sometimes right there, and if not there is normally a good blood trail.

Anyhow, I read a theory not too long ago, can't remember where. The gist of it was that if a deer runs or not (on a lung shot) is to some extent dictated by whether it had exhaled or inhaled, or was in the process of doing one or the other when the bullet did it's thing. I'm not a man of science, but it does ring true on some level. If somebody can remember where I might have read this it may provide some level of insight.

Nice to be here btw. I've lurked for a good while now. Good discourse here.
