Abstract: A shotshell comprised of shot pellets of different densities and materials which provide increased effectiveness at both close and long range. Preferably the pellets are disposed in longitudinally stratified layers, with the more dense pellets located rearwardly of the pellets of lesser density. The pellets having the greater density maintain a closer pattern at long range, because they are preferably made of tungsten which has a high density and are located rearwardly, while the pellets having lesser density are preferably made of steel, describe a much wider pattern because of their lower density and forward location, and are therefore most effective at close range.

Abstract: Nontoxic, biodegradable injection-molded, plastic shotshell components, and method of manufacturing same, the components having a fused degradation composition comprising as its active ingredients polycaprolactone, amide stearate and vegetable oil, the latter two enhancing the degradation activity of the polycaprolactone and imparting injection-moldability thereto.

Abstract: An improved sabot bullet for use primarily in connection with shotgun shells which includes a slug having a forward portion which radially converges towards the middle portion thereof, and an outer conforming sabot casing which includes a pair of sabot segments which substantially surround and conform to the outer configuration of the slug. Each sabot segment is constructed to be slightly radially spaced from the slug near the constricted middle portion thereof, and to converge and engage the radially diverging portion of the slug near the forward end thereof, so as to cause the slug to be guided mainly at a point adjacent the front end thereof. Each sabot segment is also constructed to extend rearwardly beyond the rear end of the slug to facilitate rearward movement of the slug relative to the sabot, and consequent outward radial wedging of the sabot segments against the inner walls of the gun barrel, upon firing the fireman.
