Roto and Roy: Helicopter Heroes

From bullet history dating back from the earliest guns to the present, to information on how to create your own projectiles, this guide provides in-depth coverage, all focused on ballistics

This fascinating book starts with the basics, going back to the days of muzzle loading before considering the various attempts made through the centuries to improve the bullet. It moves on to examine the development of the cartridge right up to the present day, and provides the reader with a clear understanding of the principles governing the bullet's flight. Topics discussed include the development of the bullet and the cartridge, and the factors that influence ballistic performance and accuracy. The difference between internal ballistics—factors influencing performance while the bullet is still in the barrel—and external ballistics—factors affecting the bullet's flight when it leaves the barrel—are explained. This title also aims to assist those enthusiasts who make their own bullets by analyzing faults that have an impact on accuracy, both for rifled firearms and for smooth-bore guns. A number of interesting experiments are described concerning performance and accuracy. Included in the back is a glossary that incorporates rifle terminology and those terms specific to the shotgun.
