Abstract : A method of eliminating secondary muzzle flash in small and large caliber weapons through use of a novel ammunition propellant composition comprising a conventional double base extruded propellant as well as more energetic nitramine composition and a microencapsulated oxamide coolant additive for cooling the gases exiting the weapons barrel. In the preferred embodiment, the oxamide is encapsulated with a gelatin and the resulting microcapsules are coated with a plastic resin, e.g., Bakelite TM. It is the principal object of the invention to provide a novel gun propellant which will eliminate secondary muzzle flash while avoiding smoke production and interference with the burning characteristics of the gun propellant. It is another object of this invention to provide a novel microencapsulated propellant additive which will pass through the propellant flame zone intact and decompose during its passage through the barrel to cool the exiting gases so as to eliminate muzzle flash. A further object of this invention is to provide a method for eliminating muzzle flash without interfering with the propellant burning behavior or increasing smoke production. (Author)
