A shotgun shell has a polymer wad with a forward shot cup portion and a rearward propellant cup, the wad in a casing, shot in the shot cup, propellant in the propellant cup, and a primer in a head of the casing. The propellant cup having a plurality of fins extending rearwardly that open to a deployed position upon firing and the shot cup having a plurality of circumferentially spaced axially aligned linear slit segments that permit air to circulate and permit expansion of the shot cup.

Shotshell having wad with enhanced fin deployment

Shotgun wad

A shotgun shell has a polymer wad with a forward shot cup portion and a rearward propellant cup, the wad in a casing, shot in the shot cup, propellant in the propellant cup, and a primer. The rearward propellant cup portion having enhanced fin deployment such that the shells are operative with shotguns with no chokes, shotguns with ported chokes, and shotguns with conventional chokes. The forward shot cup portion has axial slits that are sized to preclude shot from passing therethrough while providing sufficient air circulation to provide compaction relief of the shot pack. The enhancement may include gussets on the fins, axially movable disks to engage cam surfaces on the fins and urge them outwardly, and fins that have reduced bending regions compared to prior art wads.
