This document discusses wound ballistics of rifled firearms. It begins by introducing forensic ballistics and the different types: internal, external, and terminal ballistics. It then discusses wound ballistics, focusing on the mechanism of injury when a projectile strikes a living target. Key factors that influence the transfer of kinetic energy are explored. Different types of gunshot wounds are defined, including penetrating, perforating, and wounds that are both penetrating and perforating. Cavitation effects and characteristics of entry and exit wounds are also summarized.
