Nate, I've been amazed how game animals can run so far with both lungs and or the heart shot out.
I once attended a training session on knife defence. The instructor put up a supposedly researched and referenced chart saying among other things, that a severence of the various arteries from the carotid to the humeral would result in "death" within no more than 3 seconds.
He first baulked with a red face then called me a liar when I asked how could I shoot a pig and blow both lungs and the heart to shreds, yet said pig thereupon ran for 20+ seconds, covering the best part of 200 metres!
