Another discussion, I want to hear others thoughts on this topic.
I have come to a belief in several things. Of course we are not good enough to pick and chose exactly where we hit but, consider the following:
I think... if you hit a deer with a stick, whack him good and roll him a bit, he will run like hell, get outta Dodge. That is what deer do.
If something pokes them, or smacks them a bit but isn't traumatic or violent, a deer will often kick and look around to see what just happened, and often go back to feeding or just move off a bit to assess.
A sharp arrow, going thru flesh does not hurt much at all, according to folks who have been on the receiving end of it.
I have seen that an arrow going thru a deer's rib cage or other areas with minimal bone strike will cause minimal response.
I have seen that an arrow going thru a deer's ribcage, but hitting bone (ribs, leg) causes more trauma and more response. In this case, the deer might run for 20 - 80 yards, then stop in cover and watch it's backtrail, often bedding there and dying there.
I have seen that a deer hit poorly due to a deflection (i didn't miss..did I ) with a resultant broken bone, especially a leg bone, causes all out panic and a run for a long time.
Does it stand to reason then, that a somewhat slower, heavier arrow, with a cut on contact head would likely cause less initial trauma (barring the broken bone scenario) to the deer and maybe a bit less reaction / trailing need ?
Whereas a much faster lighter arrow, fronted by an expandable head, would cause much more initial trauma (don't confuse this with damage) and maybe resultant response from the deer ?
What do you think ?
