Abstract
A unitary plastic wad structure for use with a shotgun. The wad includes a shot cup portion and an obturating cup portion with both cups being of cylindrical configuration. The wad further includes a shock absorbing filler comprising transversely, obliquely, and longitudinally oriented planar members. The deflection characteristics of the transverse members provide the repeated attainment of a predictable shot pattern.
