    摘要: A cartridge comprising an elongate rifle bullet with a plurality of circumferential grooves having overmolded polymer therein defining embedded polymer rings. The cartridge further having a case and propellant. The polymer rings have an outer surface that is flush with, that is, conforming to the outer surface of the body. The polymer may have be selected to have a favorable coefficient of friction with respect to the barrel. The bands offering reduction of the metal to metal contact between the bullet and the barrel while not diminishing the ballistic coefficient of the bullet.

    摘要: Aspects of the disclosure are directed to manufacturing an insert-molded expanding projectile. Aspects of the disclosure include locating a portion of a projectile body within a converging tip mold, the projectile body including a metal jacket extending from a tail portion to a nose portion and surrounding an interior solid core. The metal jacket and nose portion may be tapered in a forward direction to an annular forward edge defining an opening to an undercut interior cavity. Melted polymer may be injected into the converging tip mold and allowed to cool thereby forming a polymer tip having a main portion forward of the opening and a tip retention portion filling the undercut interior cavity and having a shape corresponding to the undercut interior cavity to retain the polymer tip in place.

    摘要: A cartridge comprising a bullet, the bullet providing a radially expanding array of bullet fragments upon entering a target and also providing an increase in effective surface area of the bullet within the target by structural features that facilitate tumbling or mushrooming in the target. In an embodiment a pair of axial core members are aligned in a bullet jacket with the forward core member being segmented with separation junctures formed by engaged faces of adjacent segments. Impact causing fracturing of the segments from a base portion.

    摘要: A system for firing reduced energy cartridges from a modern sporting rifle utilizes a bolt assembly weighing less than a conventional bolt assembly for such rifles and utilizes blow back for cycling the bolt assembly rather than gas operation. A bolt insert in a polymer bolt carrier of the bolt assembly has a projection that fits within a recess on the rear face of reduced energy cartridges. The reduced energy cartridges having a polymer casing, a rimfire power load for propellant, the power load recessed from the rear face of the casing. The power load seats in in the casing surrounded by a reinforcement liner embedded in the polymer casing.

    摘要: An example charging handle comprises a body having a handle portion, a bolt engaging portion and a shaft portion extending forwardly from the handle portion to the bolt engaging portion. The handle portion of the body may have a starboard arm extending away from the shaft portion in a starboard direction and a port arm extending away from the shaft portion in a portward direction. The charging handle may comprise a grip member disposed about the handle portion of the body so that the grip member encapsulates the handle portion and the handle portion is disposed inside the grip member. The grip member may comprise a thermoplastic material overmolded on the handle portion of the body.
