80
- the ignition component of cartridge primers are used for igniting propellant. A blow from the firing pin on the prime cup compresses the priming composition to detonate.
- This detonation produces flamme which passes through the vent or flesh hole in the cartridge case, igniting the gunpowder.
Primer
81
also called, CAP
- is the ignition system of the cartridge used in a center fire type, containing a highly sensitive chemical compound that would easily ignite or bursts into flame when struck by the firing pin. It may either be Berdan or Boxer type.
- It is also known as the percussion cup.
Primer
82
is a type of primer construction , which was designed in 1860s by Colonel Hiram S. Berdan of the U.S Army Ordinance Department

small metal cup, into which the primer mixture is loaded. The capsule that is open to one side, into which the anvil and the primer ignition material are inserted.
Primer Cup
89
serves to ignite the main powder charge.
Priming Mixture
90
(Foil) acts as a shield for the pellet, protecting it from moisture and other disruptive influences that may effect performance or reliability.
Paper Disc

the point against which the priming compound is crushed to detonate the primer. An internal metal component in a boxer primer assembly against which the priming mixture is crushed by the firing pin blow.
Anvil
92
allow the flash of the primer to reach the inside of the case and ignites the gunpowder. The explosive ignites and shoots a flame through the flash hole, igniting the propellant to fire the cartridge.
Vent/Flash Hole
93
Types of Priming Mixture Compound

2. Non-corrosives
94
one consisting potassium chlorate added with antimony sulfide and mercury fulminate, which when ignite produces moisture causing formation of rust in the bore of the firearm.

99
Two of the most popular individual whose name is always attached to gunpowder discovery, were
Roger Bacon and Berthold Schwartz.
100
the oldest known explosive, was initialy made from saltpeter (75%), charcoal (15%) and sulfur (10%).
Black powder
101
It is a propellant which when fired, produces large volumes of grayish smoke and considerable amount of residue left in the barrel of the gun.
Black powder
102
Black powder have three qualities which are typicat in all explosives
1) when ignited, it will burn rapidly by itself, without the aid of the air outside.
2) in burning, it gives off a large amount of gas
3) A considerable amount of heat is produced
103
a propellant which when fired, does not give off huge cloud of white smoke like black powder.
- It is the most powerful propellants.
