Introduction. For forensic ballistics is important to reconstruct the events of the use of firearms. One way of reconstruction is based on the position of spent cartridges relative to surrounding objects. Often required to establish the fact of secondary reflection in the collision of objects sleeves and find a place on the collision who after this microtraces. Goals and objectives.

Introduction. Microscopic research methods play an important role in forensic ballistic examination. Theoretical analysis. To carry out the linear and angular measurements of the following fields on the rifling shot bullets used various technical tools and techniques: eyepiece micrometers stereoscopic microscopes, measuring microscopes instrumental, rolling bullets on copy paper, etc. However, these tools do not always allow you to effectively solve the task. Experimental part.

Introduction. In order to meet the objectives for establishment of circumstances of the shot, the process of experimental shooting when shooting firearms propose a new design of a special device, allowing to obtain more accurate information about the gunshot residue in studies of objects with a complex shape of the outer surface.

Introduction. The article touches upon the issues related to the need to implement a methodological relationship between judicial ballistic examination and one of the subtypes of medical and forensic examinations – forensic ballistic research, in forensic examinations and in conducting scientific research and methodological developments, and in professional training of specialists, which is expressed, first of all, in ensuring the uniformity of the conceptual and terminological apparatus and algorithms of forensic experts research facilities not related

Introduction. A promising direction in forensic practice is the use of three-dimensional modeling of objects to establish the circumstances relevant to the criminal case. Theoretical analysis. Photographs taken during the investigation could be used as a source of information to derive a three-dimensional model. Photogrammetry is a method that allows for the automated construction of three-dimensional models from images.

Introduction. The growing number of military and civilian models of firearms equipped with muzzle devices actualizes the expert diagnostics of the facts of using silent shooting devices during committing crimes by their traces on the fi red bullets and fi red cases. Theoretical analysis. Science has identifi ed a number of regularities of the eff ect of silent shooting devices on the mechanism of formation and characteristics of traces on bullets and cartridge cases.
