US12736315 - Jacketed projectile and method of manufacture

Provided is small arms ammunition projectile ( 24 ) and manufacturing method having a core ( 10 ) with a longitudinal core axis, a forward portion ( 18 ), and a rearward end ( 14 ). The core ( 10 ) has a rear portion ( 16 ) with an edge ( 26 ) that may be chamfered or radiused, a first portion ( 28 ) being frustoconical, and a second portion ( 30 ) adjacent the first portion ( 28 ) being substantially cylindrical. The jacket ( 12 ) has a longitudinal axis ( 99 ) and longitudinally extending socket ( 45 ) to receive the rear portion ( 16 ) of the core ( 10 ). The socket ( 45 ) has a socket bottom ( 46 ), a first socket portion ( 50 ) being frustoconical, and a second socket portion ( 52 ) adjacent the first socket portion ( 50 ) being substantially cylindrical. The core ( 10 ) and jacket ( 12 ) are shaped such that when assembled, the frustoconical portion ( 28 ) of the core ( 10 ) is seated in the frustoconical portion ( 50 ) of the socket ( 45 ) of the jacket ( 12 ), respective contact surfaces ( 31, 41 ) of the second portions ( 30, 52 ) of the core ( 10 ) and jacket ( 12 ) mate together with the longitudinal core axis ( 98 ) and longitudinal jacket axis ( 99 ) being coaxial.

The patent describes a small arms ammunition projectile consisting of a core and jacket designed for precise alignment, featuring a frustoconical shape that enhances the fit between the two components. The manufacturing method ensures that the core’s longitudinal axis is coaxial with the jacket’s axis, promoting stability and accuracy during firing.

Claim 1

1 . A small arms ammunition projectile made from a core and a jacket, comprising: the core having a longitudinal core axis, a forward portion, a rear portion and a rear end, the rear portion having an edge, a first portion adjacent the edge, the first portion being frustoconical and the edge being steeper in angle than the frustoconical first portion, and the rear portion further having a second portion oppositely adjacent the first portion; the jacket having a longitudinal axis and a socket extending in a direction of the longitudinal axis to receive the rear portion of the core, the socket having a socket bottom, a first socket portion, the first socket portion being frustoconical, and the socket having a second socket portion adjacent the first socket portion; and wherein the core and the jacket are shaped such that when assembled together, the first portion of the core is seated in the first socket portion of the socket, and respective contact surfaces of the second portions of the core and the jacket mate together with the longitudinal core axis of the core and longitudinal jacket axis of the jacket being coaxial. the core having a longitudinal core axis, a forward portion, a rear portion and a rear end, the rear portion having an edge, a first portion adjacent the edge, the first portion being frustoconical and the edge being steeper in angle than the frustoconical first portion, and the rear portion further having a second portion oppositely adjacent the first portion; the jacket having a longitudinal axis and a socket extending in a direction of the longitudinal axis to receive the rear portion of the core, the socket having a socket bottom, a first socket portion, the first socket portion being frustoconical, and the socket having a second socket portion adjacent the first socket portion; and wherein the core and the jacket are shaped such that when assembled together, the first portion of the core is seated in the first socket portion of the socket, and respective contact surfaces of the second portions of the core and the jacket mate together with the longitudinal core axis of the core and longitudinal jacket axis of the jacket being coaxial.
