Provided is a polymer jacketed projectile with metal core. The projectile includes a metal bullet core and a monolithic polymer bullet jacket surrounding a portion of the bullet core. The jacket includes a series of radial driving bands cut into the jacket in a graduated configuration at increasing thicknesses. The graduation and increasing thickness of the driving bands allows gradual radial acceleration upon engraving of the rifling due to intentional radial deformation of the forward driving bands. Additionally, the bullet core) includes high-friction surfaces formed in a longitudinal direction or at a base of the bullet core. The modified surface increases friction between the bullet core and polymer, further decreasing radial slippage.

Provided is a modular directional charge system that can be assembled in different configurations depending on the target. The system includes a removable energetic material, a molded plastic shell comprising a main body and a front cover, a removable fragmentation insert, a removable breaching insert, an initiator well insert, and initiator adapter nuts. The main body comprises an internal energetic material receiving compartment, a first and second tripod mount, a threaded adapter, and a pair of pin receivers, while the front cover comprises an internal removable insert compartment. The main body and front cover are held together with a multi-position adjustable toothed locking interface that adjustably permits the cover to intimately contact the energetic material when the internal removable insert compartment contains a fragmentation insert, a breaching insert, or no insert at all. A method of use is also provided.

Modular scalable effect munition

Various embodiments of optimized subsonic projectiles are provided. For example, one exemplary subsonic projectile can include an elliptical nose cone, a cylindrical body and a boattail with various design features that can be used in a subsonic ammunition cartridge where the subsonic projectile is stabile throughout at least a segment of a flight allowing for better accuracy, maintaining low drag, maximizing range and achieving desired performance while ensuring the projectile stays below the speed of sound and lowering a noise profile of projectile and a launcher firing the projectile.
