ABSTRACT:
A universal pyrotechnical percussion compositions used in rimfire ammunition and in cenerfire ammunition primers which is free of lead and other heavy metals. In the PCC of the present invention, the task of maintaining ecological purity of its burning products, absence of corrosion action on a barrel, increased shelf-life, with simultaneous increase of energetic parameters of primer and ballistic characteristics of a shot is achieved. The composition includes a base mixture of diazodinitrophenol, tetrazene and an inert organic or glass stablizer. To this base mixture, monopotassium styphnate or potassium dinitrobenzofuroxane is added. The mixture so created has a specific gravity of less than 1.7 grams per cubic centimeter.
