85
This is the most common type of FMJ bullet. It has a rounded tip and a flat base and is typically used for target shooting and training.
round nose
86
This specific ammunition is completely covered in a metal jacket and features a flat nose at the front of the bullet. The flat nose increases the surface area for impact and is helpful when protecting yourself or hunting.
full metal jacket flat nose
87
This FMJ bullet has a tapered base that reduces drag and improves long-range accuracy. It is commonly used in military and long-range shooting applications.

consists of jet black and rather shiny grains.

103
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
104
serves to ignite the main powder charge.
charge/primer compound/primer mix/pellet
105
(Fol) acts as a shield for the pellet, protecting it from moisture and other disruptive influences that may effect performance or reliability.
paper disc
106
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
107
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
108
parts of the primer
primer cup
priming mixture
anvil
disc or thin paper or foil
109
anvil is built into the primer pocket of the case, rather than the primer. These cases cannot be de-capped and reloaded by standard reloading tools.
berdan type
110
Its anvil forms part of the cartridge case and a number of flasholes to serve as the passage of ignition usually two (2).
berdan type
111
The primer pocket in the case head has a single flash-hole in its center, This positioning makes little or no difference to the performance of the round, but it makes fired primers vastly easier to remove for re- loading
boxer type
112
the boxer type was developed by
Col. Edward M. Boxer
113
the berdan type is made by
Col. Hiram S. Berdan
114
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
115
composition of primer
potassium chlorate 45%
antimony sulfide 23%
fulminate of mercury 32%
116
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 flame which passes through the vent or flesh hole in the cartridge case, igniting the gunpowder.
primer
117
three qualities of 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 and,
3) A considerable amount of heat is produced
