Abstract
A method and improved propellant composition for eliminating secondary mue flash in small and large caliber weapons without the increased smoke production or inhibiting burning characteristics through the step of incorporating a novel microencapsulated organic coolant additive into a conventional propellant composition wherein the microencapsulated coolant will survive the propellant flame zone intact so as to decompose down barrel to cool the bases exiting the weapon barrel. The preferred organic coolant is oxamide microencapsulated within a gelatin wall material and coated with Bakelite.TM..
