Abstract:
Herein we describe embodiments of shotgun shells, methods for loading such shotgun shells, and methods for using them. In some embodiments, the shotgun shells utilize a multi-component wad system with a biodegradable powder wad that stays intact through the firing process, and a separate and chemically distinct biodegradable shot wad that breaks apart within one meter after being shot out of the barrel of a shotgun. A clean release of the shot can be obtained, providing both high performance and biodegradability. The biodegradable shot wad can be a biodegradable polyester.

Claim (Index 16):
A method of shooting a shotgun shell comprising:\n providing a shotgun shell having a boundary defining an enclosed space and powder, shot, a biodegradable powder wad, and a biodegradable shot wad confined within said enclosed space, wherein said biodegradable shot wad surrounds said shot within said enclosed space within said shotgun shell, and wherein said biodegradable powder wad physically separates said powder from said shot; providing a shotgun having a barrel; loading said shotgun shell into said shotgun; firing the shotgun, whereby the shot, the biodegradable powder wad and the biodegradable shot wad are launched out of said barrel to expose said biodegradable shot wad and said biodegradable powder wad to a terrestrial or aquatic environment, wherein said biodegradable wads biodegrade; wherein said biodegradable shot wad comprises a biodegradable material; wherein said biodegradable powder wad comprises a biodegradable material; wherein said biodegradable powder wad is physically and chemically distinct from said biodegradable shot wad; and wherein upon firing of said shotgun shell from the shotgun, said biodegradable powder wad stays intact and does not break apart during flight or landing, and said biodegradable shot wad breaks apart into multiple discrete pieces during flight or landing.
