Ammunition efficiency or bullet stopping power is bullet’s characteristic which determines the enemy’s ability to execute hostile action after having been hit by a bullet (e.g. in hunting-animal’s ability to attack or move). Huge bullet stopping power, first of all, means fast elimination of the target from battlefield, but not necessarily its death. In order to understand this characteristic, one should realize bullets’ operating principles, i.e. bullet is a front part of projectile expelled from the barrel of a firearm due to powder gas. Bullet stopping power is one of the basic criteria for evaluation of short range guns (e.g. pistols, revolvers, shotguns) and depends on bullet‘s speed, size, weight, geometry and constructional features. Bullet stopping power is as stronger, as faster it disrupts functions of a living organism, which directly depends on the bullet’s kinetic energy absorption level. That is why bullets with blunt end have great stopping power. They tend to penetrate into body quite not deep, fast slow down and create a powerful shock wave, which causes temporary pulsating cavity and contusion of a nearby organs and soft tissue. On the contrary, bullets with sharp end penetrate deeply and evenly slow down cutting soft tissue rather than fraction them. This type of bullets usually causes perforating injury, but if vital organs were not damaged, does not eliminate enemy from the battle at once. Bullet stopping power of small caliber bullets is increased due to transfer of gravity centre to a posterior part. As a consequence of small ballistic stability, such bullet starts to roll and causes great pain shock.
