Bullet, bullet jacket and methods of making

Abstract

A bullet, bullet jacket, and method of making the bullet and bullet jacket. The bullet jacket comprises a predominantly copper outer shell and a predominantly zinc lining. The bullet comprises the bullet jacket and a bullet core. The bullet jacket is made by forming a predominantly copper sheet and a predominantly zinc sheet. The two sheets are then adhered to one another by cladding or roll bonding, and shaped such that they can fully encase a bullet core. The bullet is then made by using conventional means to seat and enclose the bullet core within the bullet jacket of the present invention.

         10 . The bullet jacket of  claim 6 , wherein the predominantly copper layer comprises no less than about 70% by weight of the weight of the bullet jacket.  
     
     
         11 . A bullet, comprising: a bullet core having a core shape, a layer of predominantly zinc and a layer of predominantly copper adhered to the layer of predominantly zinc, with the adhered layers surrounding the bullet core such that the predominantly zinc layer is adjacent to the bullet core.  
     
     
         12 . The bullet of  claim 11 , wherein the bullet core consists essentially of lead.  
     
     
         13 . The bullet of  claim 11 , wherein the predominantly zinc layer of the bullet jacket is roll-bonded to the predominantly copper layer.  
     
     
         14 . The bullet of  claim 12 , wherein the predominantly zinc layer of the bullet jacket is roll-bonded to the predominately copper layer.  
     
     
         15 . The bullet of  claim 11 , wherein the predominantly zinc layer of the bullet jacket is cladded to the predominantly copper layer.  
     
     
         16 . The bullet of  claim 12 , wherein the predominately zinc layer of the bullet jacket is cladded to the predominantly copper layer.  
     
     
         17 . The bullet of  claim 11 , wherein the predominantly zinc layer comprises no more than about 30% by weight of the weight of the bullet jacket.  
     
     
         18 . The bullet of  claim 12 , wherein the predominantly zinc layer comprises no more than about 30% by weight of the weight of the bullet jacket.  
     
     
         19 . The bullet of  claim 11 , wherein the predominantly copper layer comprises no less than about 70% by weight of the weight of the bullet jacket.  
     
     
         20 . The bullet of  claim 12 , wherein the predominantly copper layer comprises no less than about 70% by weight of the weight of the bullet jacket.  
     
     
         21 . A method of making a bullet jacket, comprising the steps of: 
 forming a predominantly zinc layer;    forming a predominantly copper layer;    adhering the predominantly zinc layer to the predominantly copper layer; and    shaping the adhered layers into a form capable of receiving a bullet core such that, when a bullet core is placed in the formed shaped, the predominantly zinc layer is adjacent to the bullet core.    
     
     
         22 . The method of making the bullet jacket of  claim 21 , wherein the step of adhering the predominantly zinc layer to the predominantly copper layer comprises roll-bonding the predominantly zinc layer to the predominantly copper layer.
