[Forensic characteristics of traumatic cartridges of caliber 18×45 mm and 18.5×55 mm of the OSA complex].

The purpose of the work is to show how, from the day it was created, the cartridges for barrelless firearms of limited destruction of the OSA complex changed. The main structural changes of cartridges of caliber 18x45 mm and 18.5x55 mm, affecting the nature of damage to the human body, are noted. It is shown that the general patterns of damage from modern bullets without a metal core are in many respects similar to the damage resulting from the firing of bullets of old specimens with a metal core. General recommendations are given for assessing the damage caused by pistols of the OCA complex.
