The subject of the present invention is lead- and barium-free propellant charges with primary explosives mixed with oxygen-supplying substances, characterized in that the primary explosives are selected from alkali metal and/or alkaline earth metal salts of dinitrobenzofuroxanes and the oxygen-supplying substances are chosen from metal peroxides, nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyanodiamidine, and the elements sodium, potassium, magnesium, calcium, cerium, and/or multivalent metal oxides. The propellant charges according to the invention exhibit increased stability with respect to known propellant charges that are free of harmful substances. 1 From: Von Kreisler, Selting & Werner, Patent Attorneys To: Dynamit Nobel GmbH Explosivstoff- und Systemtechnik Kaiserstrasse 1 53840 Troisdorf Date: Oct. 27, 1995 Our Reference: 951355de HPJ/ko 0321

EXAMPLES 
 Example 1 This example describes a propellant charge for an anvil percussion cap with a 20 mg load. A mixture of 45 parts by weight of potassium dinitrobenzofuroxanate, 5 parts by weight tetrazene, 30 parts by weight zinc peroxide, 15 parts by weight stannous dioxide, and 5 parts by weight of titanium was homogenized with 22 parts by weight of water and metered by smearing on perforated plates. After being placed in percussion caps, the mixtures were dried and pressed. The flammable mixture according to the invention, when stored in moisture and heat at a temperature of 71° C. and an atmospheric humidity of 90% for 7 days, exhibited better stability than a conventional diazol-containing propellant charge. No expulsion of the primer cap from the cartridges was observed during the sensitivity test. 
 Comparison Example 1 A mixture moistened with water and composed of 40 parts by weight of diazodinitrophenol, 15 parts by weight of tetrazene, 8 parts by weight of zinc peroxide, 35 parts by weight of glass powder (120 to 170 &mgr;m), and 2 parts by weight of Adhesin • (adhesive) were tossed into .221 fB rim fire cartridges, 18 mg each. The propellant charge required a varnish layer of 3 to 4 mg Vinnapas • A50 as wadding for reliable complete ignition, said layer containing 0.2 mg vanillin to characterize the odor. 
 Example 2 Similarly to Example 1, a propellant charge for .221 fB rim fire cartridges, 16 mg each, was produced. A mixture of 47 parts by weight of potassium dinitrobenzofuroxanate, 10 parts by weight of tetrazene, 8 parts by weight of zinc peroxide, 34 parts by weight of glass powder (90 to 200 &mgr;m), and 1 part by weight of Adhesin • (adhesive) was processed similarly to Example 1. The propellant charge burned through without covering varnish as wadding and achieved internal and external ballistics comparable to those of commercial ammunition.
