56 x 45 mm Rota-ammunition was introduced to meet the requirements of security personnel at prisons. The Austrian military assault rifle (StG 77) can be used for this ammunition. The bullet consists of an X-ray dense plastic material with a weight of 1.6 g. Therefore the kinetic energy of this projectile is lower than that of the standard ammunition, also on its flight it loses velocity at a higher rate. Thus, this bullet has the advantage of being less dangerous over long distances (500 m versus 2500 m or more) but still offers at short distances (fe 10 m) a reasonable capacity of incapacitation. Tests concerning ballistics, penetration and shooting at gelatine and soap targets were performed. By means of these tests we compared the wounding capacity of the standard ammunition (5.56 x 45 mm S-cartridge) and the investigated Rota-ammunition.
