features of formation of a temporary pulsating cavity at a contact shot from the fort 12rm pistol in the dressed simulator of a human torso

Current knowledge of forensic medicine on gunshot wounds is quite limited, as every year new models of weapons and ammunition for it enter the market, which accordingly requires experimental research in this area. We should also note the rapid development of non-lethal weapon, work on research which is few in the world scientific literature.Aim of the work. To determine peculiarities of the formation of a temporary pulsating cavity caused by shots from «Fort-12RM» pistol at contact distance into a human torso imitator dressed in cotton knitwear clothing. Materials and methods. To achieve this goal, 12 human torso simulators were made and dressed in cotton T-shirts. Later, a series of shots was done using a nickel-plated Fort-12RM pistol equipped with .45 Rubber cartridges. To determine the volume of the traumatic effect of the projectile, a transverse (relative to the wound channel) incision of the injury was carried out, with the formation of blocks 1 cm thick, after which they were photographed and generally accepted calculation methods were used. Results. It was found that the smallest depth of penetration of the bullet was 4 cm, while the greatest depth of penetration of the bullet was 6 cm. On the studied models, the largest size of the temporary cavity was at the depth of cut from 3 cm to 5 cm. The peak of traumatic force falls to a depth of about 4 cm. Conclusions. The data obtained can be further applied not only to replenish theoretical knowledge on wound ballistics and an idea of the processes that occur when a bullet passes through the human body, but also for practical purposes, such as identifying firearms, ammunition, determining the distance of a shot, and the like. It is important to conduct further research using other types of weapons, clothing, imitators of other body parts and different firing distances.
