Abstract

A shotshell comprising an elongate casing defining an internal chamber, a propellant located within said casing, and a shot load within the casing, the shot load comprising a plurality of disc-shaped projectiles, arranged in the casing so that the plane of each of the disc-shaped projectiles is generally perpendicular to the longitudinal axis of the casing, and a plurality of generally spherical projectiles disposed in the casing behind the generally disc-shaped projectiles.

Claims

exact text as granted — not AI-modified
1 . A shotshell comprising:
 an elongate casing having a longitudinal axis, and a head;   a propellant located within said casing; and   a shot load within the internal chamber, the shot load comprising a plurality of generally disc-shaped projectiles, arranged in the casing so that the plane of each of the generally disc-shaped projectiles is generally perpendicular to the longitudinal axis of the casing, and a plurality of generally spherical projectiles disposed in the casing behind the generally disc-shaped projectiles.   
     
     
         2 . The shotshell according to  claim 1  wherein there are at least three generally disc-shaped projectiles. 
     
     
         3 . The shotshell according to  claim 2  wherein there are four generally disc-shaped projectiles. 
     
     
         4 . The shotshell according to  claim 1  wherein the diameter of each of the disc-shaped projectiles is at least about 75% of the internal diameter of the casing. 
     
     
         5 . The shotshell according to  claim 1  wherein the weight of each of the generally disc-shaped projectiles is at least 50 grains. 
     
     
         6 . The shotshell according to  claim 1  wherein the diameter of each of the generally spherical projectiles is between about 0.08 and about 0.2 inches. 
     
     
         7 . The shotshell according to  claim 1  wherein the total mass of the generally disc-shaped projectiles is between about 50% and 220% of the total mass of the generally spherical projectiles. 
     
     
         8 . The shotshell according to  claim 1  wherein the total mass of the generally disc-shaped projectiles is between about 33% and about 70% of the total mass of the load. 
     
     
         9 . The shotshell according to  claim 1  wherein the generally disc-shaped projectiles weigh at least as much as 00 buckshot. 
     
     
         10 . The shotshell according to  claim 1  wherein the generally disc-shaped projectiles weigh at least as much as 000 buckshot. 
     
     
         11 . The shotshell according to  claim 1  wherein the shotshell is sized to fit .410 bore, and wherein the shell contains three generally disc-shaped projectiles. 
     
     
         12 . The shotshell according to  claim 11  wherein the generally disc-shaped projectile has a generally central cylindrical section within a diameter, with first and second sides, and a generally frustoconical projection on each of the first and second sides. 
     
     
         13 . The shotshell according to  claim 11  wherein each of the generally disc-shaped projectiles has a diameter of about 0.4 inches and a height of about 0.25 inches. 
     
     
         14 . The shotshell according to  claim 13  wherein the generally disc-shaped projectiles are made substantially of lead, and have a weight equal to 000 shot. 
     
     
         15 . The shotshell according to  claim 1  wherein each of the generally disc-shaped projectiles is copper plated. 
     
     
         16 . The shotshell according to  claim 1  wherein there are twelve generally spherical projectiles, each the size of a standard BB shot. 
     
     
         17 . The shotshell according to  claim 1  wherein the generally disc-shaped projectiles comprise more than 60% of the weight of the load. 
     
     
         18 . A .410 bore shotshell comprising:
 an elongate casing with a front end and a back end, and a longitudinal axis extending therebetween,   a head at the back end of the casing;   a propellant located within said casing; and   a shot load within the internal chamber, the shot load comprising of at least three generally disc-shaped projectiles, each of the generally disc-shaped projectiles weighing at least as much as a 00 buckshot, and being arranged in the casing so that the plane of each of the generally disc-shaped projectiles is generally perpendicular to the longitudinal axis of the casing, and a plurality of generally spherical projectiles disposed in the casing behind the generally disc-shaped projectiles.   
     
     
         19 . The .410 bore shotshell according to  claim 18  wherein each of the generally disc-shaped projectiles weights at least as much as a 000 buckshot. 
     
     
         20 . The .410 bore shotshell according to  claim 19  wherein each of the generally disc-shaped projectiles has a diameter of about 0.4 inches and a height of about 0.25 inches. 
     
     
         21 . The .410 bore shotshell according to  claim 18  wherein there are twelve generally spherical projectiles, each the size of a standard BB shot. 
     
     
         22 . A generally disc-shaped projectile for shotshell, the generally disc-shaped projectile having a generally central cylindrical section, with first and second sides, and a generally frustoconical projection on each of the first and second sides. 
     
     
         23 . The generally disc-shaped projectile according to  claim 22 , wherein the generally central cylindrical section has a diameter of about 0.4 inches, wherein the generally disc-shaped projectile has a thickness of about 0.25 inches.
