5.45 mm submachine gun cartridges

    The investigations performed in USSR at the beginning of 1960 have shown that close grouping of shots from submachine gun is determined mainly by cartridge impulse and weapon feedback energy. It has been established that the most real way to increase firing efficiency of the personal weapon can be fielding new cartridge with reduced impulse and development of the following generation submachine gun corresponding this cartridge.
     Creation efforts of 5.45mm submachine gun cartridges were carried out at "Central scientific research institute of precise mechanical engineering together with Design Bureau Of Automatic Lines, Tula Cartridge Works and Ministry of Defence organizations.
     Development of 5.45 mm cartridges was carried out with a glance of the international humanitarian right norms. Under such conditions have been provided sufficient bullet stability at trajectory and high damaging action.
     The increasing of muzzle velocity bullet from 725 m/s (AKM) up to 900 m/s (AK74) has led to significant improvement of grazing fire (direct shot range increasing) from new weapon. Smaller flight lime for the same range promoted firing mistakes reduction at shooting on the moving targets and at a lateral wind. The smaller feedback impulse has provided the best close grouping of shots by automatic fire. All this has provided increasing target hit probability. Reduction of cartridge weight has allowed increasing manpack ammunition in 1.5 times at the same weight.
     5.45mm cartridge with ordinary (steel core) and tracing bullet has been accepted on arms simultaneously with automatic device AK74 at 1974. Blank and dummy cartridges have been developed in addition to live cartridges. Perfection of 5.45mm cartridge was spent from 1990 up to 2010 at direction of its penetrative action Increase (for a steel core bullet) and also increase of tracing range and tracer ignition delay (for tracer cartridges).
     All the Russian 5.45mm submachine gun cartridges are produced with the steel cartridge case covered by green colors lacquer.
