Answer 2

CARTRIDGE

Question 3

It also refers to a loaded shell for rifles, muskets, carbines, shotguns, revolvers, and pistols from which a ball bullet, shot, shell, or other missile may be fired by means of gunpowder or other explosives. The term also includes ammunition/cartridge for air rifles (Sec 877 Revised Administrative Code).

Answer 3

CARTRIDGE

Question 4

The earliest small arms ammunition or cartridge consisted of a pre-measured charge of powder wrapped in a paper. The term cartridge is derived from the word “Charta,” the Latin word for paper, and from the French word “cartouche,” meaning a roll of paper, which indicates that the original cartridges were not the brass gilding metal of today’s modern ammunition.

Answer 21

Center fire
Rim fire
Pin fire

Question 22

In 1858, the Moors cartridge marked the development of center fire cartridge The priming mixture is located or contained in the center area of the base of the cartridge. Its primer could either be Boxer or Berdan.

Answer 22

1. Center-Fire.

Question 23

This type of cartridge was invented in 1845, by a French gun maker, Louis Nicolas Auguste Flobert.

Answer 23

2. Rim-Fire,

Question 24

The priming mixture of this kind of cartridge is in the cavity, inside and around the rim or the circumference around the base of the cartridge. This rim-fire cartridge is usually applied to caliber 22 pistols, caliber 22 revolver and caliber 22 rifle.

Answer 24

2. Rim-Fire,

Question 25

In this type, a pocket of fulminate is placed on the sidewall of a copper case. The pin in this kind of cartridge is already resting in the priming mixture called fulminate. The pin is to be driven by the hammer to strike and detonate the sensitive chemical compound.

Answer 25

3. Pin Fire.

Question 26

It is a part of the cartridge usually located at the center of its base and housed by the pruner pocket.

Answer 26

Primer

Question 27

This part contains a highly sensitive chemical that will produce ignition or heat when the firing pen strikes it. This reaction is termed percussion.

Answer 27

Primer

Question 28

The heat or ignition produced will pass through the canal called a vent or flash hole towards the gunpowder. Consequently, the gunpowder will be ignited and undergo combustion.

Answer 28

Primer

Question 29

Parts of Primer

Answer 29

Priming cup Priming mixture Anvil Disc

Question 30

This is the container of the priming mixture, anvil, and dise.

4. Disc

Question 35

TYPES OF PRIMER ACCORDING TO CONSTRUCTION

Answer 35

Berdan Boxer

Question 36

It is invented by the US army Col Hiram Berdan. The primer of this type, has two vents/flash holes towards the gunpowder.

Answer 36

1. Berdan.

Question 37

is non- replaceable since the anvil of the primer formed an integral part of the cartridge case and will be deformed after firing

Answer 37

Berdan primer

Question 38

It is invented by the British army Col. Edward M. Boxer. The primer has only one vent or flash hole towards the gunpowder.

Answer 38

2. Boxer.

Question 39

can be replaced and reused since the primer cup is removable from the cartridge. Thus, it is not expensive.

Answer 39

Boxer primer

Question 40

CLASSES OF PRIMER ACCORDING TO PURPOSE

Answer 40

Corrosive Non-corrosive

Question 41

contains a chemical compound that produces plumes, vapor, and chloride after the explosion. One of the chemicals in this type of primer is potassium chlorate, which produces potassium chloride when ignited by the primer flash. Potassium chloride draws moisture from the air and this moisture speeds rusting of the gun barrel.

Answer 41

1. Corrosive

Question 42

contains a chemical compound inside the primer cup that produces plumes of metal, vapor, and oxygen that form a spherical and irregular shape after the explosion. One of the chemicals in this type of primer is barium nitrate. It is a non-corrosive type of priming compound.

Answer 42

2. Non-corrosive

Question 43

is a compound contained in a cartridge that is responsible for propelling the projectile.

Answer 43

GUNPOWDER

Question 44

This compound will undergo combustion when ignited by the flash that came from the primer. Since a sealed container encloses it, the heated gas produced from combustion will develop tremendous pressure. It is also known as a propellant.

Answer 44

GUNPOWDER

known as the black powder, was invented by Roger Bacon.

Answer 45

In 1248, gunpowder,

Question 46

Two Types of Powder in Small Arms

Answer 46

Black powder Smokeless powder

Question 47

It is easily activated by heat and friction. Thus, it is the most unsafe type of powder to keep. A large volume of smoke and residue left in the barrel of the gun can be produced by this type of powder. It is also known as the oldest explosive.

Answer 47

1. Black Powder

Question 48

- It is a propellant that does not give off a massive cloud of white smoke like black powder when fired. It is the most potent propellant in small arms

Answer 48

2. Smokeless Powder

Question 49

It has two main classes of smokeless powder are?

Answer 49

Single base propellant or nitrocellulose Double base propellant has nitrocellulose and nitro-glycerine

Question 50

It only contains pure nitro- glycerine gelatinized with nitrocellulose. This type of propellant has a perfect shape in grains like small squares, discs, flakes, strips, pellets, or perforated cylindrical grains.
