1. A gas generant composition comprising:between about 30 and about 60 wt % of a non-azide gas generating fuel, between about 15 and about 55 wt % metal ammine nitrate oxidizer, between about 2 and about 10 wt % metal oxide burn rate enhancing and slag formation additive, and between about 0 and about 35 wt % ammonium nitrate supplemental oxidizer, wherein the metal ammine nitrate oxidizer is present in a greater relative amount than the ammonium nitrate supplemental oxidizer and wherein the gas generant composition provides a burn rate in excess of 0.45 inches per second at 1000 psi and a gas output in excess of about 3 moles of gas per 100 grams of the composition.
