I'm 68 and, like several others here, I have shot rifles and shotguns for the better part of my life. I learned early and well to concentrate on the target and see through or past the sights.
Last year I got into Practical Shooting. I now belong to two clubs, shoot every week during the summer, and twice a month now that it's cold. I'm retired with lots of time and two ranges within 12 miles. I'm having almost limitless fun. And, I am improving. Concentrating on the front sight and trying to see how often I can watch the sights rise is coming to me, albeit slowly.
But I have the most basic question that no one has answered for me. What is the logic/science/philosophy behind focusing/concentrating on the front sight? I fully understand it's the thing to do, but why?
