Caseless ammunition with internal propellant

Abstract

This invention describes ammunition that does not have a case but rather, utilizes the bullet itself for containing the propellant. The bullet is made of high strength material such as steel so as to withstand the explosive force of one or more types of propellant contained therein. The propellant is in a generally solid state so that it is effectively retained within the bullet. One or more types of propellant especially those having highly explosive characteristics may be layered within the bullet and ignited such that the bullet is propelled with a velocity equivalent to current ammunition. The bullet could be loaded manually or mechanically into a firearm such as a rifle or pistol just as current ammunition is loaded therein. Firing is accomplished by the purposeful ignition of the propellant by impact, spark, heat or other methods within current state of the art.

1 . Ammunition for a firearm comprising a bullet and a propellant: 
 said bullet being generally cylindrical in construction and having a sidewall, a blunt point at one end, and an aperture at the other end,    said bullet having dimensions suitable for its placement within the barrel of a firearm,    said bullet being retained in said barrel in position for ignition of said propellant,    said aperture being the terminus of a cavity in said bullet,    said cavity in said bullet being a container for said propellant,    said propellant having ingredients that undergo chemical reaction upon ignition,    said propellant being placed into and retained within said cavity,    said propellant being capable of being purposefully ignited by a device within the firearm into which the said bullet is placed,    said propellant ingredients undergo a chemical reaction of its materials when said ignition    occurs causing said bullet to travel down said barrel and be expelled from said firearm,    said bullet being made of hard material having high tensile strength such that no significant dimensional are caused by the chemical reaction of said propellant within said bullet.    
   
   
       2 . Ammunition according to  claim 1  having said propellant being composed of one or more individual explosive mixtures that undergo chemical reaction essentially in sequence upon ignition of one of said mixtures.  
   
   
       3 . Ammunition according to  claim 2  having each said mixtures undergo an exothermic chemical reaction with the result being the generation of a relatively large volume of gas that propels the said bullet from said firearm at a high rate of speed.  
   
   
       4 . Ammunition according to  claim 1  having said propellant nearest said aperture being relatively solid so to retain the propellant within said bullet.  
   
   
       5 . Ammunition according to  claim 1  having said bullet being composed of one or more materials of such composition and dimension so it can withstand the chemical reaction of the said propellant without significant change to the dimension or integrity of said bullet when said bullet is within the barrel of said firearm.  
   
   
       6 . Ammunition according to  claim 1  having said bullet being made of steel.  
   
   
       7 . Ammunition according to  claim 5  having said sidewall of said bullet be coated with one or more layers of one or more materials so as to conform to any rifling within said barrel as the bullet travels there through causing said bullet to rotate along its axis.  
   
   
       8 . Ammunition according to  claim 7  where the said materials do not cause significant damage to said barrel as the bullet passes there through at a high rate of speed.  
   
   
       9 . Ammunition according to  claim 7  where the said materials may be lead, tin, zinc, copper, an alloy or other material.  
   
   
       10 . Ammunition according to  claim 1  where said bullet has one or more circumferential depressions in the exterior of said cylindrical sidewall surface.  
   
   
       11 . Ammunition according to  claim 10  where one said depression could cooperate with means within said firearm to remove said bullet from within said barrel.  
   
   
       12 . Ammunition according to  claim 10  where one said depression could be used to position said bullet at a specific location in the barrel of a firearm by cooperating with means within said barrel.  
   
   
       13 . Ammunition according to  claim 10  where one said depression could be used to position said bullet at a specific location by cooperating with means within said barrel and also cooperate with the same means to remove said bullet from said barrel.  
   
   
       14 . Ammunition according to  claim 3  where all said propellant within said bullet is expended while the bullet is within the barrel of said firearm.  
   
   
       15 . Ammunition according to  claim 3  where a portion of said propellant within said bullet is expanded while the bullet is within the barrel of said firearm and the remainder of said propellant is expended after said bullet has exited the barrel of said firearm.  
   
   
       16 . Ammunition according to  claim 3  where said propellant comprises one or more of these substances, smokeless gunpowder, tri-nitro-toluene, tetryl, ammonal, amatol, cyclonite, and or other similar explosive materials.
