OK, simple terms, when you pull the trigger a small thing called a firing pin is driven into the back of the cartridge casing.
A cartridge is the container for the charge of gunpowder (or other sort of propellant chemical). It holds the bullet, which seals the cartridge tightly at one end, and the initiator, called a primer (which contains another type of explosive chemical, very sensitive to being hit by things like firing pins), which explodes or burns very quickly and starts the main charge of propellant burning (or exploding, usually just a very very fast burn in modern propellants - safer that way).
The propellant turns into hot gases as it deflagrates or explodes, gases which build up pressure quickly in the interior of the cartridge.
At some point the pressure exceeds the friction which is holding the bullet on to the end of the cartridge. The bullet is pushed quickly up the barrel of the weapon. If it is a "rifled" barrel, it has shallow twisting grooves (imagine screw threads inside a pipe) which engage a portion of the bullet as it passes up the barrel, causing it to twist.
Once the bullet leaves the end of the barrel, this rotation stabilizes it in flight to a great degree (gyroscopic effect), making it more accurate to a longer range than (most) smooth-barreled weapons.
That's what happens when things go boom. In a general sort of way. |
