Underwater special-purpose ammunition is a specialized bullet for underwater firearms. A cylinder is located in the center of the bottom of the cartridge case; the space between the cylinder and the cartridge case wall is the ammunition chamber. The portion extending from the cartridge case is conical and penetrates the bullet. The hollow, conical bullet fits snugly against the cylinder in the cartridge case to form a complete bullet. When the bullet is propelled out of the cartridge by the thrust generated by the combustion of the ammunition, the bullet separates from the cylinder. Because the bullet is hollow, it experiences minimal head-on resistance in water. Furthermore, the outward-angled design at the top of the bullet creates a bubble effect, further reducing drag as the bullet moves within the bubble. These two effects combine to allow the bullet to travel efficiently through the water, achieving long-range firing. The bullet and cartridge case of this invention are formed by compression and adhesive bonding. This invention does not alter the conventional primer design.
