Two books, "Instinct Shooting" and "Lucky McDaniel's Secrets to Shooting", are devoted to McDaniel's training techniques. He was written about in a wide variety of magazines, particularly in the 1950s, including "Time", "Saturday Evening Post", "Sports Illustrated" and "Guns". Nevertheless, McDaniel left behind him a stream of thoroughly bewildered customers and journalists. They understood that they had been taught to perform spectacular feats of marksmanship within an extremely short training period, but they could not match up McDaniel's training techniques with anything else in their experience because his techniques flew in the face of the conventional wisdom of that era regarding both the ways by which humans learn to perform manual skills, and the then-mutually agreed upon physical limitations of human capabilities.
