How do primers in ammo work? What are they made of?
Anyone here know a thing or two about gun ammo? Anyway, I have just been wondering on exactly how primers worked. This is how I made mine.
"Sorry if I seem like a lot of questions)
The Cartriage is a section of a copper pipe, the bullet is made from a fishing weight, the propellant is match powder. Since match powder does not go off with impact,I made the primer from a thumbtack, a strip of tin(can), and a roll cap(those red paper things that explode when you hit them with a hammer). The cap and the match powder hold the thumb tack in place. The strip of tin holds the roll cap. When the thumbtack is struck, the thumtack hits the roll cap cuasing it to create a small explosion. When the roll cap explodes, it ignites the match powder around it. This larger secondary explosion is the one that propells the bullet forward.
It works on homemade automatics, the only thing is that the catriage gets stuck sometimes, it produces A LOT of smoke, it takes around a half a second for the match powder to ignite and to propel the bullet forward, and after a while, a layer smelly brown tar begins to accumulate in the barrel.
Is this a bit simmilar to how primers work?
