Abstract
Abstract A high density armor piercing projectile having a cylindrically-shaped penetrator core. The core has a length substantially greater than the diameter thereof. Encompassing the penetrator is a carrier body and nose. The carrier body being press fit on the penetrator core and having a stabilizing ring press fit thereon. An obturator and pusher plate are secured to the rear of the penetrator core. In addition, the design of the carrier body enables the projectile to be spin stabilized when fired from any suitable weapon.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
197 words
A high density armor piercing projectile comprising a high density penetrator core, said penetrator core being of a length substantially greater than the width thereof and being tapered at one end thereof and having a substantially flat surface at the other end thereof, an indentation being formed within said flat surface of said penetrator core, a carrier body encompassing said penetrator core and having one end thereof located adjacent said flat surface of said core, the other end of said carrier body being of a conical configuration, an enlarged annular segment formed about the midpoint of said carrier body for engaging the barrel bore of a weapon, a stabilizing ring encompassing said conical end of said carrier body and being displaced a predetermined distance from the shoulder of said enlarged annular segment of said carrier body, a lightweight nose being mounted on said tapered end of said penetrator core and abutting at an end thereof said stabilizing ring, a flat pusher plate mounted against the rear flat surface of said penetrator core, said pusher plate having a nipple thereon, said nipple fitting within said indentation in said penetrator body and an obturator mounted on said pusher plate.
Claim 2
Dependent Claim
