Abstract : The stability of combustible cartridge cases (CCCs) which are extensively used in the high caliber tank gun ammunition is one of the major requirements for their safe handling and storage. The results of stability tests by heating of CCC samples at elevated temperatures and observations for change in colour of the CCC samples have been discussed. It has been observed that there are drastic changes in the colour of the CCC samples. The original pale yellow colour of the uncoated internal surface was changed to dark green. Similarly, original yellowish-brown colour of external surface coated with shellac varnish was changed to dark greenish-brown.
