First time I went bird shooting, dad spooked up a flock of English sparrows and I took a shot at the middle of the pack. I hit nothing but air. It was then I began to understand the following: you are bound to shoot what you aim at, and, if you aim at nothing, you will hit it. I should have identified a target and aimed for one bird. With me, the beginning of understanding is usually after a failure of some kind.
Having shot a hole in the wind, I learned a neat lesson about J1772.
