Description
Summary:A 105 mm lightweight plastics cartridge case consisting of an acrylonitrile-butadiene-styrene (ABS) power sidewall molded into a metal base has been developed. In production quantities it would probably be competitive in price with metallic cases. In arctic, desert and final engineering tests utilizing conventional propellants the case performed well. Minor cracking of the sidewall occurred in the arctic tests and some chambering difficulties occurred in the desert tests. No serious malfunction of firing sequences occurred under any conditions. In laboratory aging tests the acrylonitrile-butadiene-styrene polymer case was found to be fully compatible with the conventional propellants, however it was incompatible with the newer double-base propellants. Linear polyethylene which is compatible with both propellants looks promising as a cartridge case material. (Author)
