Title
(EN) DIE ASSEMBLIES FOR FORMING A FIREARM PROJECTILE, METHODS OF UTILIZING THE DIE ASSEMBLIES, AND FIREARM PROJECTILES

Abstract
(EN)
Die assemblies for forming a firearm projectile and methods of utilizing the die assemblies are disclosed herein. The die assemblies include a forming die, a first punch, and a second punch. The forming die defines a first side, a second side that is opposed to the first side, and a die cavity that extends between the first side and the second side. The first punch is configured to seal against the forming die from the first side. The second punch is configured to be received within the die cavity from the second side. When the first punch seals against the forming die and the second punch is received within the die cavity, the first punch, the second punch, and the forming die collectively define a forming surface shaped to define an external contour of the firearm projectile.

L'invention concerne des ensembles de matrice pour former un projectile d'arme à feu et des procédés d'utilisation des ensembles de matrice. Les ensembles de matrice comprennent une matrice de formage, un premier poinçon et un second poinçon. La matrice de formage définit un premier côté, un second côté qui est opposé au premier côté, et une cavité de matrice qui s'étend entre le premier côté et le second côté. Le premier poinçon est conçu pour se sceller contre la matrice de formage à partir du premier côté. Le second poinçon est conçu pour être reçu à l'intérieur de la cavité de matrice à partir du second côté. Lorsque le premier poinçon se scelle contre la matrice de formage et que le second poinçon est reçu à l'intérieur de la cavité de matrice, le premier poinçon, le second poinçon et la matrice de formage définissent collectivement une surface de formage façonnée pour définir un contour externe du projectile d'arme à feu.
