RE: Marginal hits that resulted in quick kill
The very first deer I shot with a bow was a spike that came in a little too far to my right. I drew my bow (still sitting) and when I tried to bring it around I had to really strain to get my upper body around far enough. I'm sure my form was screwed and when I released, I hit him square through the stomache. I was on the edge of a cut corn field and instead of him making straight for the woods which was what I expected, he ran straight out into the field about 60 yards and stopped and looked back. He proceeded to stand there looking back toward me for about ten seconds. Then he turned like he was going to walk off, wobbled a couple of steps and just keeled over.
I walked the same path he took into the field and never found a drop of blood or stomache matter. Had he taken to the woods it would have taken a while to find him. I still have no idea why he went down so quick.
