How do guns work? Tell me the exact process of using a gun and how exactly the gun functions, from the stage of loading the bullet to the result of hitting the target.

It really depends on the kind of gun we're talking about. This site has great info, it's one of my favorites when you want to know stuff like this. http://science.howstuffworks.com/gun-roundup.htm

In very basic terms the bullet is sealed into the front of a cartridge. The cartridge contains two different explosive compounds. The primer is ignited by the gun's firing pin and this sets off the main charge, the power of which propels the bullet from the cartridge, along the gun's barrel and (hopefully) into its target.

The projectile is pushed down the barrel by burning gasses. The rear of the barrel (called the breach) is closed, the barrel itself contains the burning powder keeping it from expanding in any direction but directly down the barrel, driving the bullet ahead of it. Depending on the type and amount of powder, the size and shape of the bullet, the projectile leaves the barrel at a high rate of speed. Because of twirlying ridges and ditches in teh barrel (called rifling) the bullet is caused to spin, which stabilizes it in flight. The whole process involves somehow igniting the power and containing the items that make up the mixture needed to send the bullet down the barrel. The container is a cartridge case which holds the means of ignition (the primer) and the burning propellant (gun powder) and the projectile (the bullet). Since this is contained in a single unit is it possible to configure the shooting mechanism many different ways, such as in a revolver, an auto-loading handgun, a rifle (many configurations). Sorry, a bit long-winded.
