  • Patent number: 7484459
    Abstract: An ammunition projectile for a firearm comprising a projectile having a nose and a cap which is designed to slow down sufficiently, when traveling through air so as to be stopped by a bulletproof vest while the projectile still has a precise and reliable trajectory. The projectile (10) has a generally truncated nose (11) and a cylindrical cap (12). The nose (11) is provided with a central, essentially circular flat section (13) which can be made larger or smaller and which has a diameter of between 10 and 50% of the diameter of the projectile at the base of the nose (11) or the cap (12). The lateral face of the truncated nose (11) is provided with five indentations (14) which are disposed symmetrically in relation to axial planes and which are obtained by one of stamping, milling, or some other suitable machining method.
