How bullet is fired, what is the roll of gun powder and trigger in bullet firing?

Answer 1

The process is simple.

Trigger is pulled
Sear is released
Hammer under high pressure spring falls forward
Hammer strikes firing pin (note: some old revolvers have the pin on the hammer itself)
Firing pin strikes primer on cartridge, denting it with enough force to detonate it (primer is a small explosive cap)
Fire from primer ignites the powder, causing it to burn
Burnt powder creates gas and much pressure
Bullet begins to move down barrel accelerated at high speed, gasses pushing it all the way

Thats it.

Answer 2

I'll explain the modern semi auto gas operated rifle

You pull the trigger, this releases a sear which strikes the firing pin. The firing pin moves forward and detonates a primer in the back of the cartridge. The primer explodes and ignites the powder in the cartridge. The gun powder burns (not explode) the rapid burn causes expansion of hot gasses. These gasses make high pressures pushing the bullet out of the barrel. Some of the gas behind the bullet are captured in a gas tub which returns some of the power to cycle the bolt back and spring forward to chamber a new cartridge.

Answer 3

OK, I'm going to break everything down into its most basic components:

A cartridge (often mistakenly called a bullet) consists of 4 components: primer, casing, powder, bullet (projectile).

Now at its most basic..... one places a cartridge into the breech of the firearm, pulls the hammer (containing the firing pin) into the locked position, person squeezes the trigger causing the hammer to fall. The firing pin strikes the primer, causing the powder to burn. Pressure from the burning powder (explosion) causes the projectile to be propelled down the barrel.

Answer 4

different guns fire bullets in different manners.

i'll describe the handheld guns like rifles and pistols, because theyre the most common now-a-days

first you have to load the bullet in the barrier.
secondly you have to c()ck the bullet into place. when you pull back the lever on the top of the gun, the bullet moves from the barrier into the back of the barrel
thirdly, you fire the bullet. this is an extremely fast reaction that occurs. a firing pin is attached to the back of the barrel and it sends a vibration into the back of the shell casing. (this reaction leaves a mark on the bullet case, which is actually used in criminal investigations to find out what type of gun the bullet came from. then after the vibration occurs, the gun powder reacts to it, and it sets off an explosion within the barrel of the gun, and the force exerted by the explosion projects the bullet out of the barrel.

i hope this all makes sense to you haha.

Answer 5

the trigger trips the fireing pin that hits the primer that ignites the gun powder that provides the compression for the repultion of the bullet . !

Answer 6

Trigger releases firing pin
Pin strikes bullet
Powder charge ignites and creates gas
Gas discharge pushes projectile out of casing and down barrel.

Answer 7

if weapons not shot bullets, then why could we've weapons? soften em down! if weapons fired 2nd opportunities, confident i could be like cupid and shoot rapidly for the midsection, the midsection is the organ this is the main harm, desires the 2nd hazard to heal and be finished!?
