ABSTRACT:
Projectiles for use in shells for shotguns and other smooth bore weapons are teardrop-shaped having a blunt hemispherical nose portion and an elongate tail portion tapering smoothly from a junction with the nose portion to a relatively sharp tip. The outer surface of the nose portion is provided with radiating curved grooves for imparting in-flight spin to the projectile so as to stabilize it in flight. The projectiles may be used in a shell case singly to provide a relatively large caliber slug or alternatively small caliber projectiles may be used in elongate stacks in a shell case to provide a form of buckshot.
