Q

How does a 5.56mm/SAA round work?

A

On functioning of the weapon the firing pin strikes the primer which is situated in the base of the case. This crushes the priming mixture against the anvil in the primer. The primer composition functions and flashes through to the propellant in the cartridge case, in turn igniting the propellant. The resulting burning produces hot expanding gases which act on the base of the projectile and drive it forward. As the projectile is driven forward, spin is imparted as a result of the external surface of the projectile engaging in the rifling of the barrel. The spin provides stability to the projectile during flight.

Q

How does a tracer round work?

A

In the case of the tracer projectile, the hot propellant gases, at the same time as propelling the projectile forward, burn through the tracer closure disc at the base of the projectile and causes ignition of the igniter composition/tracer element. This then transfers to the tracer composition which burns with a red flame to provide the firer with a visual trace of the projectile’s trajectory.

Q

** How does API-T work?

A

The burning propellant gases burn through the tracer closure disc in the base of the projectile, causes ignition of the igniter composition and tracer composition. Upon impact, the incendiary composition ignites by means of adiabatic heating resulting in igniting any flammable materials within tgt area.

Q

** How does 12.7mm MP NM140 work?

A
  • On impact and the commencement of penetration, the nose of the projectile is compressed and the incendiary composition is ignited.
  • As the projectile passes through the target, pressure continues to build within the nose and the incendiary composition ignites the HE.
  • With increased pressure build up, deflagration turns to detonation, producing blast and fragments.
  • The second incendiary charge then ignites and burns for approx. 1 second

17
Q

How many pellets and diameter are in the 12G Super-X No. 6?

A

338

18
Q

What are the minimum and maximum range for 9mm Paint FX?

A

2-200m

19
Q

** How do Centre Fire Rounds function?

A
  • On firing the pin strikes the boxer type primer
  • Crushes the anvil against the priming mixture in
    the primer
  • Ignites the composition and flashes through the
    case hole into the cart case
  • Propellant is ignited and resultant burning
    produces hot expanding gases
  • Gases act on base of projectile to drive forward
    through the barrel and act on case mouth forcing
    it outwards against breech to form a gas seal
20
Q

What is the propellant of Cart .50cal Blank F3

A

AP-70N - Double base

21
Q

What are the Main differences between Cart .50cal API M8 and API-T M20? (3)

A
  • Different propellants
  • M20 has tracer element
  • Markings on the Projectile (silver vs silver and red)
22
Q

How is the Cart connected to the proj of the Cart .50cal Ball F1?

A
  • Knurled cannelure is formed in the envelope approx 2/3rd of the way down from the tip of the projectile. The cannelure is used for crimping the mouth of the CC to the proj assembly.
23
Q

What is the Primer type of the Cart 5.56mm M855?

A

Boxer, M41

24
Q

Explain how Cart 5.56mm functions from firing to impact?

A

On functioning of the weapon, the firing pin strikes the primer which is situated in the base of the cartridge case. This crushes the priming mixture against the anvil in the primer. The primer composition functions and flashes through to the propellant in the cartridge case, in turn igniting the propellant. The resulting burning produces hot expanding gases which act on the base of the projectile and drive it forward. As the projectile is driven forward, spin is imparted as a result of the external surface of the projectile engaging in the rifling of the barrel. The spin provides stability to the projectile during flight. On impact with the target, the strength of the steel nose combined with the mass of the lead core and the overall projectile velocity, provide a penetration capability.
