  • Patent number: 6257146
    Abstract: A projectile for firing from an ammunition shell. The projectile includes an elongated hollow body of a resilient material, the hollow body further having a trailing end, a mid-portion, and a leading end, the leading end being closed and the trailing end having an aperture providing access to the interior surface. A propellant is included near the leading end of the hollow body and against the interior surface of the elongated hollow body, so that the interior surface of the hollow body between the trailing end of the hollow body and the mid-portion of the hollow body defines a hollow space. The projectile is adapted for placement within the ammunition shell to allow firing of the projectile from a shotgun or the like.
