Abstract: 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 ?/?)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; ?=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?/?)0.4 . . . (2?/?)0.
