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 41):
A method of shooting a shotgun shell comprising:\n providing a shotgun shell having a boundary defining a space, a biodegradable shot wad confined within said space, and a biodegradable powder wad confined within said space, wherein said biodegradable shot wad surrounds shot within said space, and wherein said biodegradable powder wad physically separates powder from said shot within said space; loading said shotgun shell into a shotgun having a barrel; firing said shotgun shell from said shotgun, whereby said shot, said biodegradable shot wad, and said biodegradable powder wad are launched out of said barrel; 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 said shotgun such that said shot exits said barrel at a velocity exceeding 1,000 feet per second, said biodegradable shot wad fragments into multiple discrete pieces within one meter of exit from said barrel; and wherein upon firing of said shotgun shell from said shotgun such that said shot exits said barrel at a velocity exceeding 1,000 feet per second, said biodegradable powder wad stays intact and does not break apart during flight or landing.
