Non-expanding modular bullet

Abstract

A non-expanding bullet platform may comprise a modular jacket having an internal nose cavity and an internal heel cavity. The cavities may be separated by a divider. The cavities may be filled with suitable materials to produce various types of non-expanding bullets, such as military ball, trace, armor piercing, etc. Inventive non-expanding bullets may comprise full metal jacketed bullets or may have exposed material. The inventive bullets may be non-expanding, wherein the diameter of the bullet does not substantially increase upon impacting soft tissue.

1 . A bullet comprising: 
 an outer jacket defining a first internal cavity and a second internal cavity, the jacket having a divider oriented between the first internal cavity and the second internal cavity;    a first fill material within the first internal cavity; and    a second fill material within the second internal cavity;    wherein the bullet is non-expanding upon impacting soft tissue.    
     
     
         2 . The bullet of  claim 1 , wherein the first fill material and the construction and arrangement of the outer jacket cooperate to make the bullet non-expanding.  
     
     
         3 . The bullet of  claim 2 , wherein the outer jacket further comprises a closed tip, and the first fill material comprises a material selected from a group consisting of: lead, copper, tin, polymeric matrix material and elastomeric matrix material.  
     
     
         4 . The bullet of  claim 2 , wherein the first fill material comprises a material selected from a group consisting of: hardened steel, tungsten, tungsten-carbide, depleted uranium and bronze.  
     
     
         5 . The bullet of  claim 1 , wherein the jacket comprises a material selected from the following group: copper, gilding metal and copper-clad steel.  
     
     
         6 . The bullet of  claim 1 , wherein the first fill material comprises a material selected from a group consisting of: lead, copper, tin, polymeric matrix material, elastomeric matrix material, hardened steel, tungsten, tungsten-carbide, depleted uranium and bronze.  
     
     
         7 . The bullet of  claim 1 , wherein the second fill material comprises a material selected from a group consisting of: lead, copper, tin, polymeric matrix material, elastomeric matrix material, hardened steel, tungsten, tungsten-carbide, depleted uranium and bronze.  
     
     
         8 . The bullet of  claim 1 , wherein the first fill material and the second fill material comprise the same type of material.  
     
     
         9 . The bullet of  claim 1 , wherein the first fill material comprises a hardened penetrator.  
     
     
         10 . The bullet of  claim 9 , wherein the penetrator is exposed.  
     
     
         11 . The bullet of  claim 9 , further comprising a third fill material within the first internal cavity.  
     
     
         12 . The bullet of  claim 11 , wherein the third fill material comprises an incendiary composition.  
     
     
         13 . The bullet of  claim 9 , wherein the penetrator extends from said divider to a tip of the bullet.  
     
     
         14 . The bullet of  claim 1 , wherein the second material comprises trace mixture.  
     
     
         15 . The bullet of  claim 14 , further comprising a trace module within the second cavity.  
     
     
         16 . The bullet of  claim 15 , wherein the trace module comprises a substantially cylindrical reservoir and the trace mixture.  
     
     
         17 . The bullet of  claim 15 , further comprising an end portion that is crimped about a portion of the trace module.  
     
     
         18 . The bullet of  claim 1 , wherein the outer jacket completely encases the first material.  
     
     
         19 . The bullet of  claim 1 , wherein the first material is not lead.  
     
     
         20 . The bullet of  claim 1 , further comprising a reverse ogive at a rear portion of the bullet.
