This is a book about the science of shooting guns but it also applies to archery. Beginning with the most basic science, that gravity means you can never shoot straight, it carefully and clearly explains the physical science behind all aspects of shooting. Projectile motion, the effects of air resistance and rotational motion on projectiles, the importance of projectile shapes and materials, the science behind zeroing and many other topics are explained in the basic science section. We then move on to advanced and applied science topics such as the optics of scope sights and laser sights, the impact of moving air and atmospheric disturbances on aiming. Sabot bullets, shooting up and down hill, recoil control, the science behind shooting at moving targets and other subjects are thoroughly covered. Along the way, the author includes historical asides on such topics as Custer's last stand, the Battle of Cowpens and the development of the rifle.
