| 摘要 |
The present invention relates to a primer composition formed of TNT, DNT (2,4-dinitrotoluene) and fine particle size PETN (pentaerythritol tetranitrate) for use with explosive charges. This composition is extruded in melt condition into primer cartridges. Any topping-off operations are eliminated since practically no shrinkage occurs as the melt cools to form a solid casting in the cartridge.
