When the firing pin strikes the primer, a combustible mixture ignites and the flame goes through the flash hole to ignite the powder.
Ignites the powder.
Firing pin strikes primer, primer ignites powder, powder burns and turns into gas, gas expands and pushes projectile out of the barrel
When the primer is struck, it ignites. When it does, it ingites the powder charge. The powder charge explosion pushes the bullet down and then out of the barrel.
Firing pin strikes primer, primer ignites powder in case, expanding gases push projectile down the bore.
Hangfire - A delay between the firing pin blow and the ignition of the powder, usually caused by old or contaminated primer/propellant which ignites slower than usual.
A bullet is the part of a cartridge that is fired from the gun. A cartridge consists of a cartridge case, primer, powder, and the bullet. The primer is struck by the firing pin, and explodes. In doing so, it ignites the gunpowder. Rapidly burning powder produces a rapidly expanding gas. This pushes the bullet out of the barrel.
The sound depends upon what has caused the misfire. If the primer is not ignited, the only sound will be a loud click as the firing pin strikes it. If the primer ignites but does not ignite the powder charge (which may be absent) the only sound will be a loud 'POP". If the primer ignites an insuficient powder charge (some fraction of what the normal charge would be), there will be a muffled "BANG" of much less intensity than a full charge. An experienced shooter will be able to hear and determine any of these misfire conditions.
It would probably help to define a few things.A "bullet" is only the projectile which comes out of the muzzle of the barrel and is propelled at the target.Gun powder is the propellant.The primer is a tiny explosive charge which ignites the gun powder.The case is the cylindrical object which holds the primer, powder, and bullet.A cartridge is the assembled case, primer, powder, and bulletPeople frequently say "bullet" when they really mean "cartridge".Cartridges contain gun powder, bullets generally do not.
It has a small amount of material that is sensitive to shock. When a firing pin strikes the primer, it ignites.
You activate the trigger, the hammer or striker hits the firing pin, the firing pin strikes the primer in the cartridge, which ignites the powder charge in the case.
Firing pin strikes primer, primer ignites powder, powder burns and turns into gas, gas propels the shot cup down the barrel, shot cup exits barrel and falls away from shot column at @ 7m, shot column begins to string out and form circular pattern.
