In the beginning of WW2 the military had great problems with especially pyrotechnic cartridges. Too many duds because of percussioncap failures. Investigation revealed that these were caused by ingress of moisture which caused a chemical reaction between Magnesium that produced, in combination with the sulphur of the Black Powder propellant and igniter comp hydrogensulphide gas that attacked the leadcompounds of the percussion caps. When this was realised Tetranitrocarbazol was exchanged for black Powder in many items, even in bombfuze igniters. After WW2 one does not hear about this any more and as a worldwide industry standard Black Powder again is used in these applications. Does anybody here have any explanation for this ?
