How does 12.7mm MP NM140 work?
On impact and the commencement of penetration, the nose of the projectile is compressed and the incendiary 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

What is the primer type of the Cart 5.56mm M855?
M41- Boxer
What happens on impact of the projectile from the cart .50cal API-T and API M20 with a target?
On impact with the target at high velocity, the incendiary composition ignites by adiabatic (compression) resulting in igniting any present flammable materials within the target area.
What are the main differences between the cart .50cal API M8 and API-T M20?
- Different propellant
- M20 has tracer element
- Markings of the projectile
Describe the operation of the M855 from when the primer strikes the firing pin?

- Propellant starts to burn and produces gases which act on the base and drive it forward
- Projectile driven forward
- SPin is imparted on projectile by rifling
- Provides stability in flight
- On impact steel nose and lead core provide penetration

How is the 5.56mm round work?
- Firing pin strikes primer on base of cc
- Priming mix crushed against anvil primer
- Primer comp functions
- Flash to propellant ignites it
- Propellant starts to burn and produces gases which act on the base and drive it forward
- Projectile driven forward

Incendiary
Blast
Fragmentation
How is the tracer compound ignited in cart 7.62 tracer M65 single?
The heat generated from the ignition of the propellant ignites the tracer composition.
How long does the tracer compound burn in a cart 7.62mm tracer M62 single?
Visable no greater than 140m and will burn out at approximately 775m
What is the safety warning for use of the cart 9mm training FX marking rounds?
- Min engagement distance 2m
PPE must be worn to mitigate risk of injury
What is the use of the Cart 12g Birdfrite MK2?
Clear Plastic with red cracker internal
- Dispersal of birds from ADF airfields
- Used by RAN to control crews of nearby vessels without threat of lethal force
What is the intended use of the cart 12g crowd dispersal M1013?
To disperse, dissuade and incapacitate (stun and deter) rioter.
Why is the cart 12g rifled slug rifled?
- optium contact whilst reducing wear on barrel
- allow slug to pass through barrel without deformation
Explain the functioning of a centre fired round?
- On firing the pin strikes a bower type primer
- Crushing the anvil against primer mixer
- Ignites the compostiion and flashes through case holes into cart case
- Propellant is ignited and the burning produces hot expanding gases
- Gas acts on projectile base to drive it forward and on the cart case forcing it outwards producing a gas seal

Nose of the projectile is compressed and the incendiary ignited.
Projectile passes through the target, pressure continues to build up within the nose and the incendiary composition ignites the high explosive.
Increase in pressure deflagration turns to detonation, producing blast and fragments.
