4.1. Features of fire entrance damages of coarse calico at shots ПТД-1 from a pistol "Walter"


At shots from distance in an emphasis to a tissue of target ПТД-1 from a pistol "Walter", on its facial surface round damage observed adjournment of a soot of light grey colour of the oval form, the sizes 2,0-3,0 h 2,5-3,5 sm (the appendix 13 see).
Soot adjournment on the structure were homogeneous, had indistinct borders. Below damage observed harak - ternyj a die-print in the form of a site of the arched form of dark grey colour, under the form and the size corresponding to the bottom part dulnogo an end face of a casing-shutter of a pistol (fig. 4.1).


Fig. 4.1. Soot adjournment on coarse calico at shot ПТД-1 from a pistol "Walter" in an emphasis. From top to bottom from through damage of coarse calico - the arched form a die a print of the bottom part dulnogo an end face of a casing-shutter of a pistol.
At shots from distance of adjournment of a soot of 0,5 sm on coarse calico were the wrong oval form, 2,2-2,5 h 3,0-3,3 sm, and had non-uniform character. The greatest intensity of a soot observed in the centre, along the edges of entrance damage. Colour of a soot in the centre of adjournment was the grey colour, decreasing on intensity to periphery, external contours of a zone of adjournment of a soot had rough and indistinct character.
At shots from distances in an emphasis and 0,5 sm the expressed intensive adjournment of a soot from a target underside - along the edges of damages has been noted.
At shots from distance and more visually adjournment of a soot round entrance damage on one of targets did not define of 20 sm.
On targets from the coarse calico, amazed from distances from in an emphasis to 300 sm, a wiping corbel visually it is not expressed, darkening (on - verhnostnoe serovato-black pollution) the extremities of the damaged threads of a tissue, vystojashchih in a damage lumen only is noted.
The damages arising on tissues of targets in the conditions of shot ES from a pistol "Walter" from distances in an emphasis and 0,5 sm, had the roundish or oval form, the sizes according to 10x11 mm and 12 h 10 mm. On all damages defects of a tissue («a minus a tissue») 5 h 5 mm (the appendix 14 see) have been taped by the size. Along the edges of damages defined 1-2 (in an emphasis) and 3-4 (at distance of 0,5 sm) radial rupture of a tissue in length of 2-3 mm (in an emphasis) and 12-14 mm (at distance of 0,5 sm). Visually and by means of microscope MBS round damages expressed opalenija fibers of threads of coarse calico it is not taped. Threads in edges of damages of various length, their extremities razvo - lokneny.
The damages arising on a tissue of targets at shots from distance 20, 40, 100, 200 and 300 sm had following features:
- From distance of 20 sm: damages had the roundish form, 10 h 10 mm, with defect of a tissue («a minus a tissue»), 3x4 mm. Along the edges of damages defined 2-3 radial ruptures of a tissue in length of 2-4 mm;
From distance of 40 sm: damages had the roundish form, 10 h 10 mm with defect of a tissue («a minus a tissue»), 4x5 mm. Along the edges of damages defined 2-3 radial ruptures of a tissue in length of 2-4 mm;
From distance of 100 sm: damages had the oval form, 10,0 h 10,5 mm with defect of a tissue («a minus a tissue»), 4x3 mm. Along the edges of damages defined 1-2 radial ruptures of a tissue in length 1-2мм;
From distance of 200 sm: damages had the general oval form, 10,0 h 10,5 mm, thus through damage were in a kind «P - figurative» rupture of a tissue with formation «a flap on a leg», 3x4 mm (fig. 4.2), on the one hand bridged to damage edge. Threads of a basis and a duck in a flap a little uploshcheny. Along the edges of damages defined 2-3 radial ruptures of a tissue, length 1-2мм (in the extremities of "P-shaped" rupture);

- From distance of 300 sm: damages had the general both wrong oval, and a little square forms, 10 h 9 mm. At the oval form - damage looked like "P-shaped" rupture of a tissue with "flap" formation as at described above damage from distance 200 see At the square form of damage defined 2-3 radial ruptures of a tissue in length of 2-3 mm.
As a result of the spent researches it is established, that on a surface amazed bjazevyh targets there was an adjournment of particles of products of a shot. Them defined on distances from 0 sm to 60±1,5 sm, from dulnogo a section of a trunk of the weapon, thus the greatest quantity of particles of the semiburnt down gunpowder, made 40 sm where it was revealed about 63 % from all number of particles. Rubber particles it is not taped.
