  • Patent number: 10139208
    Abstract: A jacketed tracer projectile intended for small-caliber and medium-caliber weapons includes a metal core including a tracer device, in particular in the form of a pyrotechnic tracer charge, disposed inside a cavity in the metal core in the rear part of the projectile. The cavity is designed to prevent the tracer device from becoming separated from the cavity during the discharge phase of the tracer projectile. The cross-sectional area of the cavity is typically polygonal. A method for the application of the tracer device in the tracer projectile is also provided.

  • Publication number: 20150144019
    Abstract: 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.

  • Patent number: 6286433
    Abstract: A small caliber shell having armor piercing capacity and extremely high precision. The shell includes a hollow metal shell casing defining an outer shape of the shell. The shell casing has a conical front tip and a rear end, the shell casing comprising an inner surface. An elongate shell core made of an extremely hard and heavy material is centered around a longitudinal axis of the shell between a first bearing surface on the inner surface in the conical front tip of the shell casing and a second bearing surface on the inner surface of the rear of the shell casing and is axially centered inside the shell casing. A support part is arranged inside the shell casing and surrounds at least a very rearmost portion of the shell core for supporting the shell core. A ballast material in the shell casing between the support part and an interior wall of the shell casing holds the support part in place.
