I have wondered about this for years, so maybe someone has knowledge on the subject. My nephew was hunting my farm several years ago by himself, he called me and said he had shot a buck and it was down pretty much where he shot it. I had about a 20 minute drive to go up to help him and when I walked up to the deer I could not see a bullet hole or any blood then as I was standing there the buck took a breath. I immediately told him to shoot it in the heart, I did not see it breath again. Well when we cleaned the deer only his late shot, I could not find a wound anywhere else, I searched and searched, nothing. So I finally decided that maybe the bullet may have hit a limb mushroomed out and hit the deer but had lost too much energy to penetrate. I drove up and looked and looked but no tree seemed to have a bullet scar plus only could of been a couple suspects. He shot the deer broad side at about 50 yards with a 270. Has any of you ever knocked down a deer without a wound or heard anything like this?
