US12345515 - Multi-faceted shot

Shot projectiles are disclosed that are not completely spherical. The shot has an equatorial ring, top and bottom poles, and one or more sections extending between the ring and the respective poles. The ring defines a vertical height relative to an overall diameter of the projectile. The one or more sections provide flat, concave, or convex surfaces.

The patent describes a non-spherical projectile for shotshells featuring a unique design with an equatorial ring and sections extending to the top and bottom poles, which can have varying surface shapes. The ring’s height is at least 33% of the projectile’s vertical diameter, and the sections may intersect at curved inflection points, enhancing aerodynamic performance.

Claim 1

A projectile for a shotshell, comprising: a top pole and a bottom pole defining a vertical axis extending through the top pole and the bottom pole; a body defining an exterior surface and a vertical diameter from the top pole to the bottom pole, the body comprising: an equator; a ring protruding from the equator of the body, the ring comprising a vertical ring height at least 33% of the vertical diameter of the body, an upper section of the exterior surface extending between the ring and the top pole; and a lower section of the exterior surface extending between the ring and the bottom pole, wherein at least one of the upper section and the lower section comprises two or more sections disposed at different angles relative to the vertical axis, when viewed in cross-section, and intersecting at a curved inflection point. a top pole and a bottom pole defining a vertical axis extending through the top pole and the bottom pole; a body defining an exterior surface and a vertical diameter from the top pole to the bottom pole, the body comprising: an equator; a ring protruding from the equator of the body, the ring comprising a vertical ring height at least 33% of the vertical diameter of the body, an upper section of the exterior surface extending between the ring and the top pole; and a lower section of the exterior surface extending between the ring and the bottom pole, wherein at least one of the upper section and the lower section comprises two or more sections disposed at different angles relative to the vertical axis, when viewed in cross-section, and intersecting at a curved inflection point. an equator; a ring protruding from the equator of the body, the ring comprising a vertical ring height at least 33% of the vertical diameter of the body, an upper section of the exterior surface extending between the ring and the top pole; and a lower section of the exterior surface extending between the ring and the bottom pole, wherein at least one of the upper section and the lower section comprises two or more sections disposed at different angles relative to the vertical axis, when viewed in cross-section, and intersecting at a curved inflection point.
