International Classification:

US Classification:

Abstract:

A shell formed of a casing having a propellant in it and a means of igniting the propellant, and shot formed of a plurality of metallic pellets each of a pyramid shape, that is, in the form of a polyhedron having a equilateral triangular base and equilateral faces meeting in a common apex. The pyramidal shape causes the pellets to travel in a flatter trajectory than spherical pellets commonly used so that when the shell is of the type used in a shotgun, the pellets have greater range, more directional stability, and are less affected by sidewinds.
