摘要

印度孟买法医科学实验室理事会长期以来一直在接收和检查自制/desi-katta/简易枪支。在所有这些情况下,我们的工作始终集中在各种物理参数的研究上,包括枪管参数,如长度,重量,枪口端和后膛端内径。在目前的研究中,我们处理了一个有趣的案例,一个不寻常的/无膛线的枪管,交付给印度孟买法医科学实验室理事会,没有其框架/接收器或正常发射弹药所需的其他部件(即锤,击发针,触发器等)。在没有这些组件的情况下,测试射击是通过用推杆手动接触膛膛子弹的底火来完成的,并对展示和测试发射的子弹和耗尽的弹壳进行比较显微镜。从试验射击和比较显微镜来看,从显微镜结果可以得出结论,试验射击和展示射击的子弹和消耗的弹壳是从同一支火器发射的,即使没有正常操作所需的框架/接收器或火器的其他部分。

Forensic ballistics analysis of an unusual/unrifled/homemade firearm in the absence of the action
ABSTRACT The Directorate of Forensic Science Laboratories, Mumbai-India, has been receiving and examining homemade/desi-katta/improvised firearms for a long time. In all these cases, our work is always focused on the study of various physical parameters, including barrel parameters such as length, weight, the inner diameter of the muzzle end and the breech end. For the current study, we dealt with an interesting case of an unusual/unrifled barrel which was delivered to the Directorate of Forensic Science Laboratories, Mumbai-India, without its frame/receiver or other parts required for normally discharging cartridges (i.e. the hammer, firing pin, trigger, etc.). Without these components, a test firing was done by manually contacting the primer of the chambered cartridge with a ramrod, and comparison microscopy of the exhibit- and test-fired bullets and expended cartridge cases was performed. From the test firing and comparison microscopy, it was concluded from the microscopy results that the test-fired and exhibit-fired bullet and expended cartridge case had been fired from the same firearm, even without the frame/receiver or other part of firearm required for normal operation.
