5.45x39

3D Model

ow-impulse Soviet intermediate unitary cartridge of central ignition. Developed in the early 1970s by a group of designers and technologists led by.

When designing the 5.45 × 39 mm cartridge, the developers took into account the experience in the creation and combat use of the American 5.56 × 45 mm cartridge, so the new cartridge turned out to be comparable in efficiency, despite the lower power. A small-bore bullet with a high initial velocity provides a high flatness of the trajectory (in comparison with the 7.62 × 39 mm cartridge, the direct firing range has increased by 100 meters), has a good penetrating effect and significant lethal force. A small recoil impulse at the moment of a shot has a beneficial effect on the accuracy and accuracy of fire, and a decrease in the mass of a cartridge allows the shooter to increase the wearable ammunition (200 cartridges of 7.62 × 39 mm weigh the same as 300 cartridges of 5.45 × 39 mm).
