The article studies the features of deposits of soot particles from a shot from a hand-held firearm on the front surface of an obstacle struck from different distances of the second zone of close range. Sheets of aluminum, copper or lead were used as targets, and white calico was used in part of the experiments. The microparticles of the shot products detected in the experiments were studied using light microscopes at magnifications from 300-600x to 1 250x, as well as using an electronic scanning microscope at magnifications up to 5 000x. It was found that the soot consists of the smallest poorly differentiated spherical microparticles, about 1-5 microns in size. Soot microparticles are capable of impacting the target and forming surface microcraters on its surface. The size of the microcraters depends on the power of the weapon used, the distance of the shot and the material of the barrier.
