Cartridge case deformation test

Abstract
This paper describes a re-evaluation of a very sma11-scale explosives performance test which was first developed in the 1960's. The test uses a .303″ brass cartridge case both as charge container and witness piece, and has continued in intermittent use at the UK Forensic Explosives Laboratory to the present day. In the test a small quantity of the test material is loaded into the cartridge case and initiated by a No 6 detonator. A broad performance classification is obtained by inspection of the recovered cartridge case base, and more detailed comparisons of particular explosives may be obtained by weighing the recovered bases.
