Abstract : The present invention relates to novel water-resistant consumable cartridge casing material and to methods for making same. Non-metallic, consumable cartridge cases prepared from cellulose are generally unsatisfactory due to the tendency of the cellulose to absorb moisture from the atmosphere, causing it to soften and swell and render the case weak and unfit for use. Thus, in accordance with this invention novel consumable cartridge cases can be obtained by compressing a homogeneous plastic mixture consisting essentially of (1) particles of a fibrous organic derivative of cellulose of low hygoscopicity, and (2) a polymerizable composition capable of forming a rigid, cross-linked, water-insoluble resin, into a suitable shape and thereafter curing the resin.
