With the advent of smokeless powder or residue and insensitive to water and moisture, and through capsules igniting the percussion (primers) waxy preparations nitrates, ammunition have gained ease use and reliability. The case is provided with a container full of a primary explosive capsule at its base (fulminate of mercury) and filled with a load ball is embedded in other end (cheap ammo). All named cartridge is sealed and offers ease of loading which opened the way for a series of automatic loading of weapon, thus improving its firepower.
Grenades are ammunition in form of projectiles that are typically fired from weapons such as grenade launchers, guns or mortars, or they may be hand grenades thrown by hand. Modern shells are filled with high explosives and detonate usually when they hit the target. Some types can set to explode with delay, Sometime after they have taken the target (from fractions of a second up to several days).
About a quarter of mass-produced shell failed to explode on impact, contributing to aftermath of war. During the Second World War, it will be 10 hundred shells that do not explode on impact, and about 50% of incendiary munitions. Many of them are still in soil where they decompose slowly releasing their contents (including nitrates, mercury and other toxic).
At the momentum of ball thus in a sense corresponds to weapon it went off, the same quantity of motion in opposite direction. V1equals m1 m2 v2 where m1 and v1 are the mass and speed of ball, those m2 v2 of weapon. The latter, being much heavier than the ball acquires a much lower speed, but significant: it corresponds to decrease. For a given weapon, a heavier bullet will create more distance; ammunition equal to each other, a heavier weapon present a smaller decline.
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 projectile itself may be hollow and filled with an explosive device equipped with a pyrotechnic firing (detonator react to impact or delayed), projecting shrapnel, bullets (round shot shrapnel shells) and more recently munitions. In case of chemical or biological weapons, the projectile could be filled with chemical agents or toxic pathogens, becoming toxic gases or contaminants in explosion on impact.
There is also a kinetic energy for rotation of said ball rotating on themselves. A ball rotating on itself more energy than a ball of same mass is not running at the same speed (It the same for the shell). Rifled barrels or some form of bullet lead their rotation. For information, some anti-aircraft shells 20 mm caliber rotate over 80 000 rev / min at the outlet of tube.
Century until the nineteenth century, it was necessary to calepiner rifle bullets, that is to say, wrap in a piece of cotton cloth or greased paper (cartridge) to ensure the best performance possible shooting better adjusting the projectile to bore by reducing gaps (wind) through which gases escape instead of pushing the ball, and to increase the rate of fire.
