A projectile (18) for use in ammunition for a small-bore weapon which is operated in the semi-automatic or automatic mode and which is fired subsonically and without generating of audible sound during free flight of the projectile through air. The projectile, in one embodiment, comprises a tungsten/lead powder-based core (14) having a light metal plate (20) applied to the exterior surface thereof. A round of ammunition (24) incorporating the projectile (18) is disclosed which produces subsonic velocity of the projectile during flight and sufficient energy to consistently operate the bolt mechanism of the weapon. A method for the manufacture of the projectile is disclosed.
L'invention concerne un projectile (18) servant de munition pour une arme de petit calibre, fonctionnant selon un mode semi-automatique ou automatique, qui permet un tir subsonique ne produisant pas de son audible au cours de la trajectoire libre du projectile dans l'air. Le projectile, dans un mode de réalisation, comporte un noyau (14) à base de poudre de tungstène/plomb présentant un léger placage (20) métallique appliqué sur sa surface extérieure. Une cartouche de munition (24) incorporant le projectile (18) est décrite, laquelle produit une vitesse subsonique du projectile au cours de sa trajectoire, et suffisamment d'énergie pour actionner immanquablement le mécanisme de culasse de l'arme. Un procédé de fabrication du projectile est également décrit.
