ABSTRACT:
A supplementary charge cavity is formed in the explosive charge of a high plosive projectile by: rigidly securing an open-ended tubular metal liner axially within the threaded opening or bore of a hollow projectile housing: inserting, within the liner, the shaft of a long-shafted funnel until the lower end is flush with the lower end of the liner and an annular flange on the funnel engages the end of the housing, with a liquid-tight seal between the two lower ends; pouring molten explosive material into the funnel until the housing and funnel are filled to a level above the liner, allowing the material to cool to a solid state; rotating the funnel to shear the case material at the lower end of the funnel; removing the funnel; and securing a closure disc in the lower end of the liner.
