"... I took a bead directly on that bird's head at a little over 50 feet knowing my gun shoots a bit high and having extra full choke in the gun. ..."
My "point of aim" (POA) is that spot on the neck where the feathers stop and the wattles start. I only aim at the head if that's all I can see.
I believe that is what he is saying. In the excitement he aimed at the head instead of the wattles. I have been there!
