  • Small caliber shell
    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.
