Abstract
Abstract Solid gas generating and gun propellant compositions which employ certain nitroaminotetrazole salts such as guanidinium 5nitroaminotetrazole, ammonium 5-nitroaminotetrazole and hydrazinium 5-nitroaminotetrazole as modifying ingredients in admixture with an oxidant and a suitable compatible binder material.
