A non azide gas generant composition of nitroguanidine and phase stabilized ammonium nitrate is provided. This gas generant composition has many desirable characteristics such as little production of ash and the production of essentially toxic free exhaust gas. When nitroguanidine is compressed into a pellet it has needle shaped crystals that bend or distort. When the gas generant pellets are subjected to thermal cycling some nitroguanidine crystals will return to their native conformation resulting in pellet growth. To eliminate this pellet growth, nitroguanidine is passed through a VBM mill. The media in the VBM mill pulverizes the nitroguanidine into an amorphous crumb.
