Abstract

L'invention concerne un projectile (1) pour fusil de chasse, constitué d'un corps comprenant une partie avant (2) et une partie arrière (3) creuse. La partie avant renferme une tige axiale (4) fixée par pression qui se termine par une pointe dure (6) disposée de façon frontale et présentant une configuration conique qui se termine par une forme de casque (7). Cette pointe (6) ferme l'extrémité supérieure d'une chambre à air (5) disposée de façon axiale dans la partie avant (2) du corps (1) du projectile. Ainsi, lors de l'impact du projectile, la pointe (6) se déplace vers l'intérieur de la chambre (5) et produit une compression de cette dernière qui transforme le projectile (1) en éclat. Le corps du projectile (1) est cylindrique et les cannelures hélicoïdales externes, comme le corps dont elles font partie, sont en plomb, avec une teneur élevée en antimoine. Grâce à leur dureté élevée, ces cannelures restent intactes lors du tir, ce qui, avec la partie arrière creuse (3), permet d'obtenir un projectile ayant une grande précision de trajectoire. Pour charger le fusil de chasse, on fixe le projectile sur un sabot permettant également d'amortir la pression et de bloquer les gaz générés lors du tir.
