About a month ago, I qualified in a 600-yard rifle match which was, as they say, a learning experience. There were about 20 shooters, and all were veterans, and far better shots than I. They included at least one Distinguished Expert, a national record holder or two, a state rifle team member, and so on. I was in way over my head. But what impressed me most about these virtuosi was not only how well they shot, but how fast.
