Comparative Study
[Gunpowder particles as a factor in a gunshot from up close].
Existence of different opinions on the role of gunpowder particles in determining close shot distance promoted the experiments with pistol "PM" and sporting fowling piece in vertical and horizontal directions at different distances from 0.5 up to 2.5 m using targets made of pasteboard and moistened photographic paper. The quantities of gunpowder particles on the targets which were calculated by stereoscopic microscope increased distinctly in vertical shot direction (from above downwards), especially at distances 2 and 2.5 m and particle flight distance rose; in horizontal shot direction distances of gunpowder particle flight didn't exceed 2-3 m.

These principles were analyzed and shown to extend the objects of medicolegal identification, which however possess certain features influencing the specific character of their investigation.
