Here is my take after Thanksgiving weekend where I missed 4 shots high and finally drilled a buck dead center kill-zone heartshot. and it walked calmly 20 yards and fell over dead. Lucky me, the place is crawling with deer to get so many shots!
All of the shots were 18-20 yards - easy.
All shots were from a 7 1/2 foot high tripod -sitting. After three misses high, I got a target and set it up and shot it from the tripod. No problem - dead on. My next shot at a deer was a miss high. What was wrong with my form?
Nothing. When I drilled the deer on the fifth shot the problem was crystal clear from the picture in my mind. That shot, I saw the arrow zip right into the spot I was focused on. In fact, I didn't see the whole deer, just the arrow hitting that spot. There was nothing else in the world in my attention besides that spot, and it's like I watched a ball of feathers just go there. The image in my mind lacks any peripheral details. Tunnel vision. total focus. Same as when I drilled the target dead on.
But, on all the high misses - I was looking at the whole deer. My mental picture memory of the shot is a very different picture of a whole deer, lanscape and all, as the arrow sails over its back. Lots of periphery details in those inmages. One was an attempted neck shot at 15 yards. I thought that would put me onto a tighter target. Shot at the whole neck - high again by 6 inches. I remember the deer standing behind the one I missed. More periphery, less focus - no spot - missed high.
Focus on the spot - until the arrow hits. Then watch the deer.
In the heat of the moment I tend to gaze at the deer and put him in my shot picture as I draw. But, picking the spot - the deer seems to almost dissappear from my attention. There is just that center of the kill zone, and my arrow ends up there.
Maurice Thompson and Saxton Pope and Howard Hill all wrote about this the same way.
I keep having to learn it every time I hunt.
