RE: Head shots?
A few years ago(OK, more than a few), while I was home on leave, a friend invited me out to his lease. I had never hunted before, but the military did a fine job teaching me to shoot. A buck walked up close to the feeder, but stopped short with his body behind a tree and his head sticking out. It was a 75 yard shot, so I took it and dropped him. My friend was upset with me for taking the shot and I now know that I could have waited a minute and the deer probably would have given me a good broadside shot.
