Abstract

Projectile for hand or shoulder firearms with a smooth or rifled barrel. The objective of this invention is to produce a light projectile of high initial velocity which relates to the accuracy of the heavier traditional projectiles. The projectile is characterised in that it consists of a homogeneous single-block piece of zinc or zinc alloy in proportions of at least 50 % of its total mass. The preferred means for the manufacture of such projectiles is casting because of the low melting point of zinc, but any other means (stamping, turning and the like) can be envisaged.

Description

ta r'rsente invention concerne un projectile pour armes à feu de poing ou d'épaule à canon lisse ou rayé. your present invention relates to a projectile for handgun or shoulder gun with a smooth or rifled barrel.

Elle comprend également les cartouches équipes de tel projectile. It also includes cartridges for such a projectile.

Le but de cette invention est de réaliser un projectile léger à grande vitesse initiale qui conserve la précision des projectiles traitionnels plus lourds. The aim of this invention is to produce a light projectile at high initial speed which retains the precision of heavier traditional projectiles.

Les composants (amorces, douilles, poudres) employés à la fabrication de ces nouvelles cartouches sont de fabrication courante. The components (primers, cartridges, powders) used in the manufacture of these new cartridges are of current manufacture.

L'emploi de ce projectile est totalement analogue aux autres projectiles conventionnels (tir à la cible, chasse, défence, etc.). The use of this projectile is completely analogous to other conventional projectiles (target shooting, hunting, defense, etc.).

Le projectile est caractérisé par le fait qu'il est constitué d'une pièce monobloc homogène en zinc ou alliage de zinc dans des proportions d'au moins 50% de sa masse totale. The projectile is characterized by the fact that it consists of a homogeneous monobloc piece of zinc or zinc alloy in proportions of at least 50% of its total mass.

Le projectile ainsi constitué est moins lourd qu'un projectile usuel de méme volume quels que soient les matériaux jusqu'alors utilisés (plomb, cuivre, etc.). The projectile thus formed is lighter than a usual projectile of the same volume regardless of the materials hitherto used (lead, copper, etc.).

Les caractéristiques de forme restent traditionnelles : cylindro-ogivale, tronconique, conique, plate, etc., ainsi que les moyens de lubrification permettent d'améliorer le glissement du projectile dans le canon de l'arme (gorge de graissage, pellicule). Toutefois, ces caractéristiques peuvent être modifiées afin de répondre à un usage spécifique. The shape characteristics remain traditional: cylindro-ogival, frustoconical, conical, flat, etc., as well as the lubrication means make it possible to improve the sliding of the projectile in the barrel of the weapon (lubrication groove, film). However, these characteristics can be modified to meet a specific use.

Le moyen préféré pour la fabrication de tels projectiles est le coulage du fait du faible point de fusion du zinc mais tout autre moyen peut etre envi sagé (matriçage, tournage, etc.)  The preferred means for the manufacture of such projectiles is casting due to the low melting point of the zinc, but any other means can be envi saged (stamping, turning, etc.).
