Introduction. The legislation of the Russian Federation does not provide for the test shooting of smooth-bore weapons by law enforcement agencies. There are no catridge-cases repository of smoothbore weapons because of low criminalistic information, which, in turn, makes it difficult to investigate crimes committed using this type of firearm. The report considers the possibility of introducing catridge-cases repository of registered smooth-bore weapons. Conceptual possibilities for implementing this solution are described. Theoretical analysis. The developed forensic markers are offered as one of the necessary conditions for the implementation of the project for the creation of catridge-cases repository of smoothbore weapons. The considered system of ballistic marking of cartridge cases of smoothbore firearms civilian and service weapons, which is intended for the rapid (operative) establishment of the number copy of the weapon from which it was shot, followed by the identification of weapons by private criminalistic features. Empirical analysis. Experimental studies with forensic markers made using various technical methods have been carried out, and criteria for their effectiveness have been analyzed, which, in an identification study, can identify individualizing criminalistic features. The possibilities of forensic identification of tracks on the cartridge case reflected from forensic markers are examined with the aim of establishing by law enforcement agencies a specific specimen of smooth-bore registered weapons. Results. By introducing criminalistic markers at the legislative level, law enforcement agencies have the opportunity to create a base for criminalistic catridge-cases repository of smoothbore registered weapons, which will increase the effectiveness of investigating crimes using this type of firearm.
