I have only had a shot at a deer with my bow once, and it was also my first shot at a buck ever. I missed it, cleanly, high. I was pretty angry with myself, but was happy that it was a clean miss. It was the only deer I saw that day. About a half hour before leaving the woods, I was getting fed up with all the squirrels around. I put my broadhead away, and knocked one of my target arrows. Put the arrow right in the boiler room of the squirrel!
I missed a deer, but plugged a squirrel. It's amazing what buck fever will do to ya.
