if a deer is relaxed when its shot - I would expect it to drop at about 60 yards with a double lung hit.
I have shot deer through the heart that didn't hear it coming; that started feeding; fell over; and one buck that bred a doe and fell off of her quite dead.
If a deer is alerted; then it will really pick um up and put them down; and cover ground. If the arrow hit where the shoulder can come back as it runs- it can keep blood from coming out as it would when the wound was not covered.
Then too; hit a bone; and the deer will travel further- due to the shock to the system. A two blade head between ribs; it is like a shaving cut; compared to taking a baseball bat and hitting a rock. ( don't try that at home).
Another thing is the arrow that does not pass through. If its swinging around or slapping the deer; it will go further.
Deer normally run from danger into the next cover; and then put their tail down; and check their backtrail: to see if they are being followed.
If they are hit they can tend to do the same thing; to run a distance and stop and look back.
A lung hit collapses the lungs; and the oxygen stops going to the brain real fast; and they hit the ground when that happens- but toss in some adrenaline and they will cover more ground.
This shows itself real well with gut hit deer. They will lay down within yards; and die there; but if they get pushed; they can run for miles.
Timing is really important in bowhunting. Waiting for a shot at a calm deer is not always possible; but always preferable!
