The objective of the present study was to compare the injurious action of three types of the bullets for the pneumatic weapons shot from different distances using the Gamo pump air pistol and the BAM B22-1 pneumatic rifle. The following four kinds of the bullets were tested: "the fireball", "Luman cap 0.3", "Luman Field Target 0.68" and "DIABOLO". ⋯ The studies by the contact-diffusion method have demonstrated that the entrance bullet holes created by the shots from pneumatic weapons are surrounded by dispersed metal particles which makes it possible to estimate the shooting distance. Moreover, the bullets fired from the pneumatic weapons leave the muzzle face imprint on certain target materials.

The objective of the present work was to study the specific constructional features of a 9.0 mm pneumatic rifle designed to use three types of bullets differing in the head shape. Also, the morphological signs of the injuries inflicted by such bullets that can serve as the prerequisites for objective differentiation of the damages are considered. The study revealed peculiarities of experimental damage to the non-biological (plasticine blocks) and biological (bio-mannequins) simulators of homogeneous human tissues inflicted by the shots from the pneumatic rifle from different distances.
