Introduction. In connection with legalization of autonomous cartridges loading to the rifled firearm, the matter of forensic examination of reloaded cases is growing more urgent. Objectives. The research is aimed at studying the regularities of trace formation on the reloaded cases during the shot from the firearm in order to diagnose the technique of cartridges producing, these cases being the cartridges parts. Experimental part.

Introduction. In connection with legalization of autonomous cartridges loading to the rifl ed fi rearm, the matter of forensic examination of reloaded cases is growing more urgent. Aims and tasks. To examine the regularities of trace formation made by the reloading equipment on reloaded cases in order to identify the method of making cartridges, whose parts they have originally been, and to establish the fact of reloading by means of the same production mechanisms. Experimental part.

A comparison microscope employing the standard optical comparison method and confocal microscopy with subsequent cross correlation topography analysis were used to correctly identify cases fired from a set of ten (10) consecutively made pistol slides. The mathematical identifications were based on the breech face impression without the firing pin aperture shear marks. Fifteen (15) unknown cartridge cases were compared to test fired cartridge case sets from the consecutively manufactured slides.
