Did you hit any bones on that shot? If not, that for sure tells me there is something else being overlooked. Even if you hit a rib, that should have been a pass-through IMO.
22 yards out, 20' up in a tree or so, which is a great angle, broadside and nothing between him but me and air and yes, I hit way high up on the rib cage, I don't think I hit backbone, just below it where the thick ribs come off the spine. Of course, hard to tell 1" from 2" below etc ....... but on impact there wasn't a loud crack like hitting ribs normally give, yet I only got 4-5" penetration or ?? Again, a deer running off its hard to tell if 24" is sticking out or if 23" is, you know ?
But, I've hunted a lot, shot a lot of game, I know when an arrow is suppose to break through and double lung - this hit should have.
It didn't - why ?
I dunno why ......... but I DO know it would have had greater chance to break through wit a few more pounds heavier bow andanother 100 grains of arrow weight behind it.
Agree or no ?
