(Fol) acts as a shield for the pellet, protecting it from moisture and other disruptive influences that may effect performance or reliability.

A

paper disc

106
Q

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.

107
Q

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.

A

108
Q

parts of the primer

A

primer cup
priming mixture
anvil
disc or thin paper or foil

109
Q

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.

A

berdan type

110
Q

Its anvil forms part of the cartridge case and a number of flasholes to serve as the passage of ignition usually two (2).

A

berdan type

111
Q

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

A

boxer type

112
Q

the boxer type was developed by

A

Col. Edward M. Boxer

113
Q

the berdan type is made by

A

Col. Hiram S. Berdan

114
Q

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.

115
Q

composition of primer

A

potassium chlorate 45%
antimony sulfide 23%
fulminate of mercury 32%

116
Q

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.

117
Q

three qualities of explosives

A

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
