Abstract
A pyrotechnic mixture for use in tracer rounds of projectiles to increase sibility under high speed conditions when viewed through laser hardened optics, comprising, in percentages by weight, an admixture of 20% to 40% magnesium, 10% to 30% strontium nitrate, 3% to 8% sodium nitrate, 3% to 20% barium peroxide and 1% to 5% viton. Additional ingredients that increase the pyrotechnic effectiveness are 0% to 5% aluminum, 0% to 15% potassium perchlorate, 0% to 5% manganese dioxide, 0% to 10% iron oxide as Fe.sub.2 O.sub.3, 0% to 15% potassium nitrate, 0% to 10% Teflon and 0% to 1% ethyl cellulose.
