发明名称 LEAD-FREE AMMUNITION FOR SMALL-BORE WEAPONS
摘要 The invention relates to a lead-free projectile (5) having improved performance and intended for small-bore weapons, configured so that the quantity of toxic metal particles and gases which is formed by the friction between the projectile (5) and the inner side of the weapon upon firing of the projectile (5) is reduced, at the same time as the performance of the projectile (5) is improved or maintained. The projectile (5) is characterized in that the core (6) of the projectile (5) comprises a front core part (7), constituting the penetrator part of the projectile (5), and a rear core part (8), constituting the ballast part of the projectile (5), wherein the front and the rear core part (7, 8) are detachably joined together with each other by a radial guide (9) configured for mutual freedom of rotation between the front and rear core part (7, 8), and in that the rear core part (8) comprises, on the one hand, a cylindrical part and, on the other hand, a conical part having a cone angle α within the range 5°-9°, wherein the contact surface between the cylindrical part and the inner side of the weapon 1 upon firing of the projectile (5) constitutes less than 30% of the total surface area of the projectile (5). The invention also relates to an improved cartridge (1) and an improved method.
