The invention relates to ammunition for missile weapon and firearm. The cavitating core of the invention comprises a head part conjugated with a secant nose surface along the cavitating edge, a central part, and an aft part with a gliding surface, wherein the caliber of the core is defined by the maximum diameter of the circle describing the core cross-section. The contour line enveloping the cross-sections from the cavitating edge to the core caliber in the plane of the core axial longitudinal section is limited by the dependence: Dx=d×[1+(1x/d)×(2×sin &phgr;/&pgr;)1/N]N, where Dx—is the current diameter of the core enveloping contour R, mm; d—is the cavitating edge diameter, mm; Lx—is the current distance from the cavitating edge to the core caliber, mm; &phgr;=60° . . . 270°— is the apex angle of the tangents to the secant nose surface at the points of its conjugation with the cavitating edge measured from the side of the head part; N=(2&pgr;/&phgr;)0.4 . . . (2&pgr;/&phgr;)0.2— is the core volume factor, wherein the core caliber is equal to the current diameter of the core enveloping contour Dx. As a result the invention makes it possible to increase the effective distance for hitting underwater targets when shooting from the air to the water and/or during underwater shooting using arbalests, harpoon guns, artillery, small and sporting-and-hunting weapons. |
