Many new types of expanding or fragmenting handgun ammunition have been developed. Knowledge of these unusual bullets may aid in the management of patients and their wounds. ⋯ Expanding/fragmenting bullets produce larger, shallower wounds than do full metal jacketed bullets. Recognition of the wound and roentgenographic appearances of these unusual bullets will help the trauma surgeon to properly treat gunshot victims. Because of the occurrence of jacket separation in water, ordnance gelatin should be used for optimal evaluation of bullet performance.
