    Abstract: Herein we describe shotgun shells each having a degradable wad comprising a polyhydroxyalkanoate polymer, as well as methods for ensuring that such wad degrades quickly after landing in an aquatic environment. Plastic, aquatic debris has a negative economic and ecological impact, and thus it is advantageous to use implements that will degrade into environmentally benign compounds. Incorporating a degradable wad into shotgun shells provides an effective, economical solution. Suitable degradable shotgun wads and methods are described herein.

    Abstract: The present invention provides a method of determining the efficiency of a gun cartridge by determining the water weight volume of the cartridge; determining the bore diameter of the gun barrel; determining the weight of the bullet; and calculating the efficiency rating of the cartridge by multiplying the water weight volume by the bore diameter and dividing by the bullet weight. The efficiency rating is optimal between 110 and 145 when the water weight volume is determined in grains, the bore diameter is determined in thousandths of inches and the bullet weight is determined in grains. One such 50 caliber gun cartridge has a casing diameter of approximately 0.688 inches and neck portion which accepts a bullet having a bore diameter of approximately 0.510 inches. The case has a length ranging from 1.75 inches to 2.5 inches measured from the primer to the mouth of the neck.

    Abstract: Ring pellets for gas generators exhibit optimum reaction rates by having configurations which optimize such rates. The pellet has a central ignition duct; from the latter, outlet channels extend radially toward a rim of the pellet. Specific embodiments contain, on the topside and underside of the pellets, either conical recesses or annular channels or both. The pellets preferably exhibit a proportion of surface area/unit weight of from 4 to 7 cm.sup.2 /g, which can be set by variation of the channels and, respectively, of the recesses to obtain a desired value. The higher this value, the greater the reaction rate. The ring pellets are especially well suited for airbag generators which must display differently high reaction rates on the driver's side and on the front-seat passenger's side, and which are to exhibit at the same time a high breaking and abrasion stability.
