Forensic value of the number of incoming gunshot injuries in the diagnosis of a ricochet

The article presents the results of a study of its own experimental data characterizing the dependence of the characteristics of input gunshot damage when fired from a smoothbore weapon and the subsequent ricochet on the angle of encounter with an obstacle. The purpose of the study was to experimentally establish the significance of such a diagnostic feature as the number of input gunshot injuries that occurred as a result of a ricochet when firing a smoothbore weapon to determine the fact of a ricochet. Ballistic experiments were carried out with the production of shots from a 12-caliber IZh-27 M hunting rifle with Profi Hunter buckshot (8.5 mm, 32 gr, 12/70) and a Gold bullet (32 gr, 12/70) at different angles of encounter with 4 types of obstacles and subsequent defeat ricocheting shells of biological and non-biological targets.
A study of the results of the experiment using applied statistical analysis methods made it possible to establish a direct dependence of the number of entrance gunshot injuries on the angle of encounter of shells with an obstacle, which can contribute to obtaining objective and scientifically based data on the conditions for the formation of a gunshot injury.
