What I have noticed. Light set up generating 60 foot lbs of KE. At 14 yards will get a pass through with a heart shot. Same set up at 28 yards another heart shot, no pass through.
What you all forget when you talk about pass throughs and kinetic energy is how much friction the arrow is trying to pass through. The heart of the deer had enough friction to stop the arrow at 28 yards but not at 14.
now if you don' t hit the heart, just lungs at 28 yards it will most likey pass through.

If you hit any shoulder bones at any range no pass throughs. Just a couple of things I have noticed with some of my setups....

I would sumise when shooting an elk I would go with slow and heavier as I would want the momemetum and extra down range energy because the elk is bigger and wider than a deer and presents more friction to the arrow as it tries to pass through.. I don' t see why you all don' t get it yet......[:@] Slower and heavier is better especially on larger animals....... Gee' s end of though end of disuccision..
not going to reply to anyone on this....
