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.
Claims8
A shell comprising:
- an ogival hollow-point bullet of maximum diameter between 0.4200 inch and 0.5100 inch;
- 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 forward from a proximal root at the base portion to a distal tip and cooperating with the base portion to define a volume for accommodating the bullet in a pre-firing condition;
- and
- a reinforcement at least partially embedded in the base portion, the reinforcement being more rigid than the molded member and having:
- fore and aft faces;
- a lateral perimeter;
- a central aperture along a central longitudinal axis of the bullet;
- and
- a plurality of additional apertures with said base portion extending through the additional apertures and being effective to retain the reinforcement within the molded member upon firing.

A sabot for firing a subcaliber projectile from a firearm, the sabot comprising:
- a molded member and having:
- a base portion;
- and
- a plurality of petal portions, each extending forward from a proximal root at the base portion to a distal tip and cooperating with the base portion to define a volume for accommodating the projectile in a pre-firing condition;
- a metallic disc reinforcement at least partially embedded in the base portion, the reinforcement being more rigid than the molded member and having:
- fore and aft faces;
- a lateral perimeter;
- a central aperture along a central longitudinal axis;
- and
- a plurality of additional apertures with said base portion extending through the additional apertures and being effective to retain the reinforcement within the molded member upon firing.
A sabot and bullet combination comprising:
- said bullet;
- and
- said sabot, having
- a reinforcement member having a plurality of apertures;
- a molded sabot body around the reinforcement member, so that material from the sabot body extends through the plurality of apertures so as to link a portion of the body forward of the reinforcement member to a portion of the body aft of the reinforcement member.
A sabot and bullet combination comprising:
- said bullet having:
- front and rear cores, the rear core harder than the front core;
- and
- a jacket containing the front and rear cores separated by a transverse web of the jacket;
- and said sabot comprising:
- a molded sabot body formed of a plastic and having:
- a base portion;
- and
- a plurality of petal portions, each extending forward from a proximal root at the base portion to a distal tip and cooperating with the base portion to define a volume for accommodating the bullet in a pre-firing condition;
- and
- a reinforcement at least partially embedded in the base portion, the reinforcement being more rigid than the molded member and having:
- fore and aft faces;
- a lateral perimeter;
- and
- at least one aperture.
