Examination of Dumped Ammunition-A Case Report by Ajitesh Pal in JFSCI - Juniper Publishers
The recovery of old firearm, ammunition, grenade, mortar etc concealed under soil/water-body is often reported. The examination of such cases by investigating agency/ballistics expert necessitates to establish various facts on them since use of such material by shooter for firing involves risk due to improper storage. The non availability of dry and cool condition and dumping under variable temperature, extreme humid condition may change the ductibility of the cartridge material, composition of the primer/propellant charges. Further, the body of such material made of different metals may get corroded/oxidized and may split/rupture when fired. The examination of such old ammunition requires to know the possible physical/chemical changes when kept under unstable environment for long years. In one case some old 9 mm ammunition were unearthed by labourers when digging soil and the investigating agency sent the recovered ammunition to the forensic science laboratory to know their condition. In order to ascertain various parameters, different examinations like indoor test firing of the ammunition, combustible character of propellant charges, elemental composition of charges by chemical analysis have been conducted. The generated data would help the shooter to take precautionary measure and ballistics expert to know the chemistry of old dumped ammunition.
