First of all it should be understood that it is FORCE that is required to push an arrow through a deer not energy or momentum. We measure force in POUNDS. ....Did I make any sense whatsoever?
P.S.
[If you're curious about why I said think about "doubling" the force... I used double because the distance through a deer (broadside) is roughly a little less than 1/2 the power stroke on a bow of a typical archer. Sorry but without writing a book on this and boring everyone further, I can't explain it any better. Hope I shed just a little light and mabe gave a little different way of thinking about this and didn't confuse everyone]
sad thing is iactully understood this...but basically every thing he just said idhave to agree with. Honestly i dont now why you would have to worry about it too much, cuase you dont have to have a pass though to kill a deer yeah im sure it help to find them but i have found both of mine and neither passed completely though, the BH did but not the entire arrow,,also one thing i found out is that with little poundage bow it is better to shot heavy arrows cuase they will penetrate deeper, just my .10
