следы на гильзах

Introduction. Authentication of the threaded shooting-iron in modern practice of investigation of crime is an actual task, therefore search development of obschemedocheskikh bases of its decision creates a scientific prospect. Theoretical analysis. In the article, on the basis of tendency of the maximal use all represented possibilities of creation of single expert method of criminalistics research of the threaded shooting-iron and tracks of his application are considered in tracks of co-operation of the identification fields of the equated objects.

Introduction. Problematic issues of providing the criminalistic requirements of the Ministry of Internal Affairs of Russia imposed to firearms are considered in work. A sometimes weapons does not provide formation on the shot bullets and cartridge cases of the traces suitable for identification. Absence of any standards or specifications on a roughness of a relief of surfaces of the details forming traces is to it the reason.

Introduction. Recently in expert practice there registered the instances of using homemade reloaded rifled weapon cartridges. Objects and tasks. To consider the regularities of trace impression formed by reloading facilities on the microrelief of cases. To detect the most stable (specific, characteristic) features reflected on the reloaded cases thus enabling to differentiate between the traces of production mechanisms and arms. Experimental part.

In work the basic ways of alteration of the gas weapon of the Izhevsk mechanical factory in fire are presented, laws of formation of traces on bullets and sleeves depending on technological features of alteration are defined. Are offered concrete technical-forensic to the recommendation about research of traces of manufacturing of the self-made weapon at carrying out of diagnostic and identification examinations.
