It happens. Congrats on getting a very nice buck. But
when they die that quickly, that is where I was aiming.
Watched a first time hunter, aim for the heart lungs. He had buck fever so bad he hit the buck in the neck just behind the ear. When we walked up on the der he said- "that is not where I was aiming". I looked him and said (shaking my head up and down)- "yes it is" if you tell your buddies that is where you aimed.
