FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to production of ammunition, as well as for designing and manufacturing of armor-piercing ammunition of various types and modifications. Armor-piercing ammunition has armor-piercing core. On its surface there are transverse-circular and longitudinal grooves of various configuration. These grooves form crests. Grooves are filled with metal with low melting point. Closest parts of the flanges with respect to the front part of the shell are made flat. Longitudinal grooves are located at the angle opposite to the inclination angle corresponding to the step – the slope of rifles for the rifled armament.
EFFECT: technical result is higher reliability of device.
