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.
