This refers to the distance within which the firer has control of his shots, meaning he can place his shots at a desired spots

When the bullet is driven by the heated gas by tremendous pressure towards the muzzle end, the bullet will rotate following the rifling or lands and grooves inside that gun barrel.

the distance that a projectile can be propelled from a firearm. The farthest distance the bullet could travel.

It is another portion of the recoil action that is characterized as the backward and upward movement takes place before the bullet leaves the muzzle

This refers to the imaginary straight distance from the muzzle of the gun to the target

Probable defects in the contents of the primer cup .

Defects in firearm that cause to misfire

Priming mixture composing what?

Cheaper, refillable, 1 flash hole

This refers to the noise created at the muzzle point or the gun by the reason of sudden escape of the expanding gas when it comes to instant contact with the air in the surrounding atmosphere at muzzle point.

Expensive, not refillable, 2 flash holes

The lands and the grooves, starting from the breech end up to the muzzle end of the barrel, will engraved in the body of the bullet, depending on the number of lands and grooves as part of the class characteristics of the firearm

The recoil of the gun is cause, by the equal and opposite reaction of the gun, against the forward movement of the bullet after the explosion

This refers to the rate of speed of the bullet (during its flight) per unit of time, and it is usually expressed in feet per second (ft/sec) and measured through the use of a chronograph machine

The distance within which a bullet is still capable of inflicting injury after it has been fired.

Lateral deviation of the bullet

The failure of the cartridge to explode after the firing pin strikes the primer is called.

Factors Affecting Trajectory

When a heated gas created by the burning powder charge is developed, a tremendous pressure is produced in the chamber of the firearm

explode several seconds after the firing pin blow the primer, the delay of explosion, is known as.

results in a downward curve path

study of the motion and traits of projectile, while still inside the gun barrel, this covers from the time, the firearm is loaded with the cartridge, the explosion and the movement of the bullet towards the muzzle end of the gun.

Stages of Trajectory

Energy is the capacity to do work. The potential energy serves as the propellant of the expanded gases, in as much as the pressure that is developed has that degree of energy to force the projectile out of the shell. It is the measure of force in foot-pound necessary for an action

It is a very sensitive chemical compound located inside the primer cup.

This refers to the actual curve path of the bullet during its flight from the gun muzzle to the target, which usually occurred a few meters away from the muzzle of the firearm called wobbling

The bullet will travel the bore of the barrel depending on the powder load of the cartridges, since it is the powder load will propel the bullet in the bore of the barrel of the firearm

After the primer crushed the priming mixture against the anvil, there will be an ignition of priming mixture and the primer flash, passes through the vent or canal towards the gunpowder

is the speed of the bullet

indoor target range

3. Ignition of priming mixture, also called.

slows its flight

To minimize the recoil of the gun, the gun owner should buy a gadget that will tend to reduce the recoil in every firing of the gun.

is the weight of the bullet

This refers to the energy generated at muzzle point measured in foot-pound. This is attributed to the hot gas liberating at the muzzle point

There will be equal expansion of heated gas inside the cartridge, after the combustion of gun powder

Is the study of the motion and traits of projectiles, after it has left from the muzzle of the gun, which includes the condition of the bullets movement, and flight up to the target
