  • Patent number: 8794156
    Abstract: A projectile package loaded in a firearm includes a projectile having a rod attached to its rear region. The rod is attached to a drag member or vanes having elastic properties. When fired, the projectile is expelled from the barrel of the firearm. Upon exiting the barrel and until the projectile reaches its effective range, reactionary air forces caused by the projectile traveling through the air result in the elastic vanes orienting themselves in a tight formation behind the rear region of the projectile. As a result, the vanes do not detrimentally affect the aerodynamics of the projectile's flight within the effective range of the projectile. However, once the effective range of the projectile has been exceeded, the slower velocity of the projectile causes the elastic vanes to laterally fan or spread out so as to impede the forward progress of the projectile.

  • Patent number: 7418904
    Abstract: The invention relates to an inert ballistic element and to a method for manufacturing it. Said method comprises the steps of: preparing a cylindrical tube, the ratio between the thickness and the outside diameter of said tube being equal or greater than 0.07; heating one end of the tube for a certain length until it is red hot; forging the end on a forging machine to form the tail and a part of the body of the ballistic element; heating the opposite end of the tube; and performing a second forging operation of the opposite part using a forging mould to form the nose of the ballistic element and to give the ballistic element its final shape. The forging operations are carried out with a forging machine equipped with a chuck that grips the tube by the non-heated end and pushes the tube into each nose or tail mould, which is divided into at least two shells that are moved by an opposite reciprocating motion.
