Abstract: An aerodynamic projectile is provided having a shell with an aerodynamic structure and a controlled center of gravity, and which exhibits improved aerodynamics and resulting accuracy, and which is suitable for less lethal uses. The projectile shell has a closed front cavity housing a payload, such as a marking agent, therein. The projectile shell also has an open rear portion to provide access to the open rear cavity, and to decrease the weight of the projectile and appropriately locate the center of gravity. The projectile shell also includes a plurality of fins on a sidewall member to enhance the accuracy of the projectile.
