The Formation Mechanism of Projectile Entry Wound on Skin

Abstract

The background of the article is a shooting experiment, which was carried out in 2017. According to our experiences, the classical explanation of the formation mechanism of entry wound on skin is not adequate. The goal was to perform a new experiment to document and analyse the formation mechanism of entry wound. The secondary topic was a comparison of the GRS and traces of smokeless propellant and black powder. Different firearms and a bow were used. The velocity of the projectiles were measured, and was calculated an average for each weapon. During the test pork knuckles were shot from the same distance. The hits were documented with a high-speed camera. The high-speed - 16-30,000 fps record shows the impact of the projectile and the reaction of the skin surface in detail. Taking into account the results, the classical explanation must be modified.
