Abstract
A two-piece firearm projectile includes a jacket and a penetrator. The proximal end portion of the penetrator is received in and mates with a corresponding recess defined in the inside surface of the jacket. A three-piece projectile includes a jacket, a slug, and a penetrator. The slug and at least part of the penetrator are encased by the jacket, where the slug is positioned between the base of the jacket and the proximal end of the penetrator. The proximal end of the penetrator overlaps axially and mates with the distal end of the slug. In one example, a frustoconical end of the penetrator is received in and mates with a frustoconical recess in the distal end of the slug or the jacket as the case may be.
Claims20
A firearm projectile comprising:
- a jacket extending along a central axis, an inside surface of the jacket defining a recess aligned with the central axis;
- and
- a penetrator extending along the central axis and at least partially retained in the jacket, the penetrator having a proximal end portion received in the recess and having a shape corresponding to the recess, wherein an interface between the proximal end portion of the penetrator and the recess is non-planar and where the recess axially overlaps the proximal end portion of the penetrator.
A firearm projectile comprising:
- a jacket extending along a central axis, the jacket having a closed base and defining a cavity;
- a slug in the cavity and contacting an inside distal surface of the closed base of the jacket, wherein a distal end of the slug defines a recess aligned with the central axis;
- and
- a penetrator extending along the central axis and at least partially retained in the jacket, the penetrator having a proximal end portion received in the recess and having a shape corresponding to the recess, wherein an interface between the proximal end portion of the penetrator and the recess is non-planar and the recess axially overlaps the proximal end portion of the penetrator.
