RE: Why did this deer expire so fast?
Actually a deer will live about30 seconds after a clean double lung or a heart shot. When the heart is hit it will stop beating, the deer will/can only run as long as the oxygen in his blood will support consciousness.
This willrun out in about 15-30 seconds or less depending on how much oxygen was in the system at the time of the hit or if the deer had just been sleeping, running, feeding,etc...
Same with a double lung, without oxygen a running deer only has seconds before it's supply is exhausted causing it to black out then die.
The thing some folks don't realize is that a deer can cover hundreds of yards in 15-30 seconds!
