Most guns have a barrel provided with internal stripes for imparting a rotation to ball to improve the stability of its trajectory. The muzzle velocity of a bullet is very variable depending on the ammunition and barrel length of arms (cheap ammo). Ammunition handguns are relatively slow their speeds hardly exceed that of sound is about 340 m / s. Ammunition long guns are much faster, between 400 and 1000 m / s. A long-range shooting also involves a time lag between the shooting and the arrival of projectile it may be necessary to compensate.
With the First World War that the industrial production now become ammunition was more than tenfold in a few months, involving a large number of financial, industrial and mineral resources of belligerents. More than a billion shells and tens of billions of pistol bullets, rifles and machine guns, torpedoes and other grenades have been made in four years. At the end of war, a third of shells coming out of manufacturing lines were chemical munitions which a small part was used.
Ammunition design is determined by its purpose. Ammunition with bullets designed to fragment in tissue when it acting, has since 1905 been strictly forbidden to use against people acc. War on Land Regulations (popular name: the Geneva Convention). This type of projectiles is required for rifle hunting, where the goal is to kill an animal as quickly and efficiently as possible; the war would be rather to put the opponent's personnel out of game without killing.
Anti-personnel grenades usually contain small metal balls, and are designed to explode in air above the enemy infantry, so grenade splinters can damage the maximum number of enemies. Ammunition is generally made of a hard material and are pointed and thin. Fire Projectiles include shells with white phosphorus, which burns vigorously. Tracer emit light and smoke on target, so the shooter can see it both in daylight and at night.
The most important characteristic of a firearm ammunition for which it chambered. It determines the caliber of weapon. The weight of ball and the amount of powder determine the power of ammunition and the recoil of weapon. The following chapters explain why modern munitions tend to be a lighter and faster than the older munitions lower caliber.
The gravity causes the projectile to ground and the trajectory of a projectile in form of a falling curve. The long distance shots require compensate for this by aiming above the target. The ball will be more speed, more seem flat trajectory for a given distance. The wind will be compensated in same way by shifting the line of sight to side. For long-range shots, it will also consider the Magnus Effect and Coriolis force.
For reasons of safety and danger, military munitions are stored in places called ammunition depot. The first gun fired simple stones or iron shot recovered in forges (before it was banned). Spherical balls were quickly invented cast in lead and lead alloy of antimony and arsenic to harden. The powder was first charged separately by mouth of gun or gun or cannon.
There are many panel discussions on the effectiveness of munitions. Multiple approaches are, for example tests in homogeneous blocks (specific gel or clay) to study the effect of impact, statistical studies and medical studies on actual cases. Several explanations are usually advanced and are hotly debated.
