A composite projectile (10) for an ammunition cartridge comprising a core (12) formed for compacted unsintered powder particulates and having opposite ends. The core (12) is encapsulated within a jacket (14) having an open end (22). A cap (16) is contained with the jacket (14) having an open end (22) thereof and is physically captured within the jacket in contiguous relationship to that end of core (21) nearest the open end (22) of the jacket (14). The cap (16) defines a fixed partition extending across the traverse cross section of the jacket that enhances the concentric positioning about the longitudinal centerline (20) of the jacket of any powder particulates dislodged from that end of the core (21) contiguous to the cap (16). The core (12) preferably is formed from a cold-compacted mixture of tungsten and lead powders.

L'invention concerne un projectile composite (10) pour cartouche comprenant un noyau (12) formé de particules de poudre resserrée non frittée, et ayant des extrémités opposées. Le noyau (12) est inséré dans une enveloppe (14) qui a une extrémité ouverte (22). Une capsule (16) est intégrée dans l'enveloppe (14) qui a une extrémité ouverte (22), étant physiquement enchâssée dans ladite enveloppe en contiguïté avec l'extrémité du noyau (21) la plus proche de l'extrémité ouverte (22) de l'enveloppe (14). La capsule (16) définit une séparation fixe qui s'étend au-delà de la section transversale de l'enveloppe et améliore le positionnement concentrique, autour de l'axe central longitudinal (20) de l'enveloppe, de toute particule de poudre délogée de l'extrémité du noyau (21) qui est contiguë à la capsule (16). Le noyau (12) est constitué de préférence d'un mélange resserré à froid à base de poudre de tungstène et de plomb.
