The author, who spent his career studying trajectories of nuclear missles and artillery shells, wrote this work after becoming dissatisfied with the accuracy of commercial rifles. Through years of research, he examined a variety of gunsmithing and handloading issues in search of the ultimate in rifle accuracy, including barrel-receiver joint motion, barrel vibration and rigidity, chamber and throat design, case neck tension, and bullet imbalance.
Good book even being 30 years old now. It does get difficult to read at times when it gets into the technical engineering talk. Best for someone who is really interested in why exactly a rifle shoots the way it does. If you’re a shooter that is happy with seeing holes in the paper and not too bothered about slightly larger group spreads and doesn’t care why, there are probably easier books to read out there.
