Abstract
Abstract A charge for a shotgun shell comprising a plurality of stacks of nesting pellets. Each of the pellets is provided with a tapered cavity in one end and a tapered outer portion at the other end, whereby the tapered portion of one pellet is insertable in the cavity of the adjacent pellet. The nesting of the pellets provides a higher packing density than is achieved with spherical pellets. The pellets are preferably made of steel. The pellets may be inserted into the shell with either the tapered end forward or the cavity end forward, depending upon the desired aerodynamic characteristics.
