Coated bullet body

Abstract

A bullet for ammunition, in particular with a caliber of at most 20 mm or at most 13 mm, may include a metallic bullet body and a surface coating with a thickness of more than 100 μm forming at least sectionally an outer skin of the bullet.

1 . A bullet for ammunition, comprising:
 a metallic bullet body; and   a surface coating with a thickness of more than  100  um forming at least sectionally an outer skin of the bullet.   
     
     
         2 . The bullet according to  claim 1 , wherein the surface coating comprises a material selected from the group consisting of copper, zinc, tin, nickel, chromium and alloys thereof. 
     
     
         3 . A bullet for ammunition, comprising:
 a metallic bullet body including: a tapered bullet front, a narrow guide band adjoining the bullet front and adapted to engage in a land-and-groove profile of a firearm barrel, and a frustoconical bullet tail adjoining the guide band; and   a surface coating covering the bullet tail at least sectionally and having a thickness increasing at least sectionally from the guide band towards the tail.   
     
     
         4 . The bullet according to  claim 3 , wherein the guide band defines a maximum outer diameter of the bullet and is cylindrical and/or transitions into the bullet tail by a transition inclined at an angle of 15° to 70° with respect to a longitudinal axis of the bullet. 
     
     
         5 . The bullet according to  claim 3 , wherein an angle of inclination of the frustoconical bullet tail in relation to a longitudinal axis of the bullet is 0.5° to 5°. 
     
     
         6 . A bullet for ammunition, comprising:
 a metallic bullet body; and   a surface coating of plastic forming at least sectionally an outer skin of the bullet and having a thickness of more than 50 μm and at most 500 μm.   
     
     
         7 . The bullet according to  claim 6 , wherein the plastic is:
 a thermoplastic plastic,   a high-temperature-resistant thermoplastic plastic,   a high-molecular thermoplastic plastic,   a thermoplastic plastic of the polyolefin class,   a polymer containing both amide and imide groups,   a polymer of the polyhaloolefin class, and/or   a synthetic polymer.   
     
     
         8 . The bullet according to  claim 6 , wherein the plastic surface coating is an immersion plastic surface coating. 
     
     
         9 . The bullet according to  claim 6 , wherein the surface coating is a galvanic surface coating. 
     
     
         10 . The bullet according to  claim 1 , wherein the bullet body comprises a tapering bullet front, and a narrow guide band adjoining the bullet front and adapted to engage in a land-and-groove profile of a firearm barrel, wherein a shoulder is formed a transition from the guide band to the bullet front, the shoulder forming a reservoir for the surface coating. 
     
     
         11 . The bullet according to  claim 10 , wherein the coating thickness in the reservoir is more than 125% of an average coating thickness of the surface coating. 
     
     
         12 . The bullet according to  claim 6 , wherein the bullet body has an elongated frustoconical bullet tail which merges into a bullet bottom by a tail cone whose inclination with respect to a longitudinal axis of the bullet is greater than the inclination of the bullet tail. 
     
     
         13 . Ammunition, comprising: an ammunition case and a bullet according to  claim 1  arranged therein. 
     
     
         14 . A method for producing a bullet for ammunition according to  claim 1 , the method comprising:
 deforming a metallic blank from a bullet body with a tapered bullet front; and   applying a surface coating forming at least sectionally as an outer skin of the bullet.   
     
     
         15 . The method according to  claim 14 , wherein applying the surface coating comprises galvanically applying the surface coating to the bullet body. 
     
     
         16 . The method according to  claim 14 , wherein applying the surface coating comprises performing an immersion process to apply the surface coating to the bullet body. 
     
     
         17 . The bullet according to  claim 1 , wherein:
 the metallic bullet body comprises:
 a tapered bullet front; 
 a narrow guide band adjoining the bullet front and adapted to engage in a land-and-groove profile of a firearm barrel; and 
 a frustoconical bullet tail adjoining the guide band; and 
   the surface coating covers the bullet tail at least sectionally and has a thickness increasing at least sectionally from the guide band towards the tail.   
     
     
         18 . The bullet according to  claim 1 , wherein the surface coating is plastic and the thickness is more than 100 μm and at most 500 μm. 
     
     
         19 . The bullet according to  claim 1 , wherein the ammunition has a caliber of at most 20 mm.
