The arrow hit about 3 inches under the spine and entered around the last rib area and did not pass through. This deer was unfortunately not recovered after 6 hours of tracking.
We used to call this area "no mans land". What i mean is?
Ihave shot deer in this area myself and never recovered them itsan area where there really is nothing vital. However you will find enough blood to keep you walking for hours. I know many hunter that have sead they have hit deer in this samearea trailed for hrs andnever recoverd them.
About the passthrew? There are all kinds of reason the arrow did not passthrew the animal all the way maby like huntingson sead it may be your setup? or the angle of the shot itself. I really don`t think that the head you sead you shot the deer with is the problem, "shockwaves" is a good head i have shot plenty of deer with themnot all of them were passthrews? But i didn`t need it as long asmy arrow hit its mark.
Most of the deer i have shot using these heads ran on ave, 20-50 yrds and fell.
However if you are looking to getpassthrews i would look at using a good well made fixed head like "magnus or slicktricks"(imo).
