Title (EN) AUTO-SEGMENTING SPHERICAL PROJECTILE
(FR) PROJECTILE SPHÉRIQUE À AUTO-SEGMENTATION
Abstract:
(EN) Described are spherical projectiles such as used in birdshot, buckshot, or single ball spherical projectiles, including slugs, muzzle loading projectiles, or any close-to-bore diameter projectile, that is auto-segmenting or self-segmenting upon impact with a target. The projectile or shot disclosed herein retains its shape and structure during flight until impact with soft tissue, whereupon its individual sections separate or segment in a controllable manner, each portion of the projectile imparting or depositing a high amount energy to the tissue and target. The auto-segmenting spherical projectiles can be frangible or non-frangible. This disclosure also provides cartridges such as shotshells that are loaded with the projectiles described herein.
(FR) La présente invention concerne des projectiles sphériques tels que ceux utilisés dans la grenaille, la chevrotine, ou des projectiles sphériques à balle unique, comprenant des balles, des projectiles à chargement par la bouche, ou tout projectile à diamètre proche de l'alésage, qui est à auto-segmentation lors de l'impact avec une cible. Le projectile ou le plomb selon la présente invention conserve sa forme et sa structure pendant le vol jusqu'à l'impact avec un tissu mou, après quoi ses sections individuelles se séparent ou se segmentent de manière contrôlable, chaque partie du projectile transmettant ou déposant une grande quantité d'énergie au tissu et à la cible. Les projectiles sphériques à auto-segmentation peuvent être désintégrants ou non désintégrants. La présente invention concerne également des cartouches, telles que des cartouches à plombs, qui sont chargées avec les projectiles selon l'invention.
