  • Patent number: 7487727
    Abstract: A bullet includes a frontward facing aperture. Contained within the aperture is a relatively hard bullet frontal element that provides advantageous bullet impact performance. In one embodiment, the frontal element is a steel sphere that provides advantageous penetration and weight retention when the bullet impacts laminated glass, such as an automobile windshield.
    Type: Grant

  • Patent number: 7302892
    Abstract: A sabot and shotshell combination includes a bullet, a shotshell hull, propellant, a shotshell primer, wadding, and a sabot comprising a molded member having a base portion and a plurality of petal portions each extending from a proximal base root to a distal tip, the base and petals defining a volume for accommodating a bullet. A reinforcement is at least partially embedded in the base, the reinforcement being more rigid than the molded member and having a plurality of apertures with the base portion extending through at least one of the apertures to retain the reinforcement within the molded member upon firing.

  • Patent number: 7007609
    Abstract: A plastic, cup-shaped, multi-petal sabot housing a sub-caliber projectile for use such as in shotgun cartridges. The sabot engages the rifling of the shotgun barrel and transfers the spin to the projectile. A reinforcement disk is advantageously at least partially embedded in a sabot base and has a central aperture and a plurality of additional apertures. Sabot base material extends through the additional apertures. Advantageously, in its relaxed condition, each sabot petal includes a protrusion from its inboard surface for engaging a projectile ogive. The protrusion and its contact area with the projectile are fractions of the local petal width.
