Disclosed is a small-bore projectile (100) comprising an outer jacket (5) made of tombac, a hard core (4) made of hardened steel, and a hollow jacket core (8) that is also made of tombac. The kinetic energy is substantially transmitted to the hard core (4) when a target (Z) is hit such that said hard core (4) penetrates the target (Z). The ductile jacket (5) is supported by the jacket core (8) that is located on the inside and mushrooms up into a deformed jacket (5') without fragmenting. The inventive projectile (100) is provided with a good flying behavior and a great final ballistic performance and can be produced in an entirely lead-free manner.
L'invention concerne un projectile de petit calibre (100) comprenant une enveloppe externe (5) en tombac, un noyau dur en acier trempé (4), et un noyau-coiffe creux (8), également en tombac. Lorsqu'une cible (Z) est atteinte, l'énergie cinétique est transmise essentiellement au noyau dur (4), de sorte que celui-ci perfore la cible (Z). L'enveloppe ductile (5) est supportée par le noyau-coiffe (8) qui se trouve à l'intérieur et s'aplatit en champignon, en formant une enveloppe déformée (5'), sans qu'il se produise de fragmentation. Le projectile (100) selon l'invention présente un bon comportement en vol et une excellente performance balistique finale ; de plus, il peut être fabriqué entièrement sans plomb.
