One Piece Shotshell

Abstract

A one-piece shotshell comprising an integral base with an opening at a first end, a sidewall extending from the base defining an open second end, and a crimp integrally disposed between the first end and second end. Apparatus and methods for making the shotshell and shooting a projectile are also disclosed.

1 . A one-piece shotshell comprising an integral base with an opening at a first end, a sidewall extending from the base defining an open second end, and a crimp integrally disposed between the first end and second end. 
   
   
       2 . The shotshell case of  claim 1  further comprising a plug closing off the first end of the case. 
   
   
       3 . The shotshell case of  claim 2  where in the plug is a primer. 
   
   
       4 . A method of making a shotshell case comprising forming a tubular body with an integral base and a crimp integrally disposed within the tubular body. 
   
   
       5 . A shotshell comprising a one-piece case having a generally cylindrical body having a first opening for receiving a plug and a second opening, a rim extending radially outward beyond the first opening of the cylindrical body, an integral crimp attached to the inner surface of the cylindrical body. 
   
   
       6 . A method of shooting a projectile from a shotshell comprising the steps of loading the shotshell with at least one projectile, said shotshell comprising an integral base with an opening at a first end and a sidewall extending from the base defining an open second end, and shooting the projectile. 
   
   
       7 . The method of  claim 6 , wherein the projectile is a pellet. 
   
   
       8 . The method of  claim 6 , wherein the projectile is a ball bearing.
