Abstract

A cartridge shell has a cup-shaped metallic case stub whose rim is internally recessed to form an annular shoulder against which an inner skirt of a polymeric sealing ring, forming an extension of that rim, comes to rest while being flush with the inner cup surface. The rim portion of reduced thickness may be adhesively bonded to the skirt internally overlying same; that portion may form an annular web with an enlarged edge bead received with a snap fit in a complementary annular groove of the sealing ring separating the inner skirt from an outer skirt concentric therewith.
