7.62 x 39 mm Russian chuck has a spindle with a full metal jacket bullet that has a copper plated metal shirt, a huge iron core, and a small amount of lead in the nose and covering the core (Sketch 1). In tissue, this bullet is usually held 26 cm straight, before you start to deviate. Typically, the channel through the abdominal cavity caused minor damage; channel in organs was similar to that produced by neekspansivnyh pistol bullets. Moderate wound leg by a bullet 7.62 x 39 mm was similar to the injury of low-powered pistol bullets: a tiny dot the inlet and outlet with the least destruction of muscle tissue.
7.62 x 39 mm Yugoslav cartridges — have a full metal jacket bullet with lead core and a flat base. Usually, before departure in a straight line moves only the first 9 cm Due lead core, smooth bullet deviates from her a few flies malehankih flattened fragments, but it is not important for the injured.
Almost always, it goes in the direction of injury tummy. You can wait three times a huge area of tissue damage than after the passage of a bullet in a straight line. In addition to the larger bullet in the body of the channel formed by deviating from the path of a bullet, the tissue surrounding the canal stretched from the temporary cavity. The real damage done by stretching cavitation could differ from the actual explosive effect, widely striking dense organs such as the liver, a single gunshot to the channel when the bullet passed cavity. 2nd case of an effect not observed when the hollow bodies of (e.g., colon) in the outlet fly off a small amount of water or air. Wound outlet opening may be elongate or dot that depends on the orientation of the bullet. Output hole could be stellate if the bullet remained significant potential. Input injured leg openings are malehankih point, but the output may be stellate when measuring more than 11 cm from the edges of the reverse. These star-shaped wound in the main cause of bleeding from the very small blood vessels, to vessels of medium size, but the temporary cavity triggers the muscles of blood vessels, allowing the latter to taper to limit blood loss. Being widely disclosed, these wounds tend to drain and astounding speed healing, even in situations of limited medical care. Such profound tissue destruction legs, of course, temporarily limit the mobility of the ill-fated.
5.45 x 39 mm. Bullet has an all-metal shell of copper-plated steel and a strong metal core, similar to the core of its predecessor, the bullets 7,62 x39 mm. A unique feature of a bullet cartridge 5.45 × 39 mm air cavity is located inside the membrane in the nose. Speculation that the air cavity facilitates deformation and fragmentation of the bullets have not been confirmed, but the air cavity provided the displacement of the center of gravity to the base of the bullet, which contributes to its very premature rejection. In addition, when faced with a cloth lead, which is behind the cavity bullet shifted backward. He called asymmetry and, perhaps, was a prerequisite for the typical curvature of the trajectory of the bullet second half of the way. The curve movement yavna only longish ranevoim channel, for example, an oblique shot in the torso. In reality, it does not have much, or significant traumatic effect, but can cause confusing wound channel in the tissue. This shot is deflected just after 7 cm of penetration into the tissue, providing greater damage from the temporary extension of the cavity in a greater percentage of boundary hits, other bullet to start the differences need to be more than the deepest penetration into the tissue, and in almost all cases, the cause minor damage in marginal hits.
Wound feet 5.45 mm bullet cartridge 7N6. Multisplintered gunshot fracture of the femur. In the field of crisis — the corresponding triangular piece nose bullets.
5,56 x45 mm. In case of contact there is a large wound cavity. As shown in the wound profile, this all-metal bullet follows a straight-line movement of 12 cm, then deflected by 90 degrees, ivy and breaks the ring (cut-out around the middle of the bullet, which solidified in Dultsev sleeve). Bullet ivy, but there is one piece that contains 60% of the mass. The back of the huge amount of broken fragments that fall by 7 cm radially from the bullet channel. Temporary cavity is stretched, its effect is due to the increased penetration, due to weakening of fragments that cause a huge number of extensions of the wound cavity.
The effects of such bullets wounds in the abdomen showed a variable cavity described for the Yugoslav bullets for AK-47, besides increasing damage due to muscle rupture and fragmentation. When searching for the channel that is comparable to the size
of the bullet in hollow organs such as the intestinal tract, always detected channel left warped cloth, which had more than 7 cm in diameter. The inlet when injured leg was small and a point. The first part of the channel showed a small bullet damage. The outlet different from the point described for bullets from Russian 7,62 x39 mm, it was stellate, the wounded Yugoslav bullet 7.62 x 39 mm. With all the dimensions of the outlet depend on the thickness of your feet, which hit. In significant thickness hip fragmentation bullet M193 also resulted in enormous damage tissue, with one or several small exit holes disposed around 1st enormous.
Injured leg 5.56mm M855 bullet cartridge. Multisplintered gunshot fracture of the femur. In the area of the fracture, numerous fragments of a fragmented bullet.
1 — Gunshot fracture of the middle third of the leg by a bullet of 7.62 mm. The deviation from the initial direction of motion bullet.
2 — Gunshot fracture of the middle third of the leg by a bullet of 5.56 mm. There is a complete fragmentation (destruction) of the bullet.
3 — Gunshot fracture of the middle third of the leg by a bullet of 5.45 mm. There is broke off the nose bullets.
The degree of fragmentation decreases with increasing distance shooting (reduced impact speed), as shown in Figure 7. At a distance of about 100 meters bullet breaks at the rim, forming two huge pieces, and shooting distance of 200 meters there is not a huge fragments, although the deformation is saved directly to 400 meters. The configuration data in the deformation / fragmentation are necessary for court professionals. They can be used to estimate the distance of firing the bullet that went into the body, broken only myagenkie tissue.
