Comparative identificational characteristic of artificial leather with embossed surface damages caused by airgun pistol pellets with different head end forms

Background: Authors of this article have made a comparative identificational description of artificial leather damage caused by air gun pistol pellets with different head end forms. Aim: This study aimed to provide a comparative identification characteristic of injuries caused by shots from an air pistol MP-53 M on artificial leather with a raised surface and a textile net glued to the wrong side at different angles and from different distances by bullets with different head end shapes (hemispherical, flat round, and conical). Used: Air pistol MP-53M, bullets with different head end shape, a fragment of black artificial leather with an embossed surface, and a textile mesh glued to the wrong side. Shots were fired at close range, 50 and 100 cm at angles of 30°, 45°, 60°, and 90°. The prevailing forms of damage (defects) of artificial skin, characteristic of bullets with a hemispherical, conical, and flat rounded head end, dependence of the form of damage (defect) on the distance of the shot, and the angle of entry of the bullet into the material. Conclusion: A comparative study showed that the form of damage to the material depends on the head end shape of bullets. Moreover, intragroup differences were found in the damage due to the distance of the shot and angle of entry of the bullet into the material in groups of bullets with the same head end shape.
