ABSTRACT:
An ammunition cartridge comprises a tubular case having a head end and an open mount end, at least two propellant charges contained within said case, and a hermetic barrier means installed between the charges for separating the charges from one another and preventing premature crossflow of gases. One embodiment of the barrier means comprises a formed-in-place solid layer of polymeric resin material. This layer is formed in place on top of a first propellant charge, conforms to the surface contour of the first charge and extends radially across the charge to the tubular case.
Another preferred barrier means comprises a collapsible flexible polymeric disk extending radially across the case between the charges. This disk has a diameter at least equal to that of the inside of said case and a tubular outer rim operably engaged with said tubular case to provide a circumferential seal between the charges.
