Abstract
Background: The article presents the results of experimental studies of gunshot injuries of biological tissue simulators in relation to the morphology of the wound channel, which depend on the characteristics of the cartridge used. Aim: To establish the features of the wound channel in the biological simulator caused by semi-shell bullets of cartridges fired from the KO-98M1 carbine under the 8×57 JS cartridge. Material and methods: Experimental shots were fired with 8×57 JS cartridges with shell and semi-shell bullets from the KO-98M1 hunting carbine. The first group of observations consisted of shots of cartridges with shell bullets of two radius ogival shape; the second group-shots of cartridges with semi-shell bullets with a head part in the form of a truncated cone. Shots with shell bullets of a single-radius ogival form formed the control group. In each group of observations, 10 shots were fired from a distance of 5–10 m, and a pig's half-carcass was used as a target. Results: In the first group of observations, the entrance injury had an oval or rounded shape, with a Central tissue defect with a diameter of 6.5±0.5 mm. the Wound channel from the entrance injury expanded conically and reached a maximum at a distance of 6 cm. In the second group of observations, the entrance gunshot injury had a rounded shape, with multiple radial tears, with a Central tissue defect with a diameter of 7.5±0.5 mm. The wound channel from the entrance injury expanded spherically immediately behind the skin, reaching a maximum at a distance of 4 cm. In the control group of observations, the entrance gunshot injury had a rectangular shape, with one or two radial breaks and a Central tissue defect with a diameter of 5.5±0.5 mm. The wound channel throughout corresponded to the diameter of the firearm shell. Conclusion: In the course of experimental studies, it was found that the rounding of the head part of the shell increases the size of the wound canal cavity by about 4 times. The runway occurs at a distance of 6 cm from the input damage. A semi-shell bullet with a head shape in the form of a truncated cone leads to the formation of a runway immediately behind the layer of skin, while the size of the visible cavity of the wound channel exceeds the size of the projectile by 15 times.
