Characteristics of Cart 0.50 Cal API-T M20 function?
- Can be used with the AIMTEST Sub-Cal Training System (Abrams Tank)
- Double base propellant
- Jacketed armour piercing projectile
- API M8 identical round less tracer element (silver/grey 16mm from tip of proj)
- AP proj is manufactured from manganese molybdenum alloy (red 8mm from tip / silver from 8-16mm)
- Alloy core machined at steeper angle at nose
- Creates a void to allow for incendiary component
- Recess in base for Tracer
- On impact incendiary composition ignites by means of adiabatic heating

How does Cart 12.7MM MP NM140/ MP-T NM160 function?
- On impact the nose of each projectile is compressed and the incendiary ignited
- As the projectile passes through the target, pressure continues to build up within the nose and the incendiary composition ignites the high explosive
- Deflagration turns to detonation, producing blast and frag. The second incendiary charge then ignites and burns for approx. 1 second
Types of Cart 12 Gauge
- Buckshot OOSG
- Super Ranger No5 Shot
- Super X No6 Shot
- Birdfrite MK2
- Birdfrite Shellcracker
- Bean Bag Standard Range
- Point Control M1012
- Crowd Dispersal M1013
2 uses of Birdfrite MK2
- Effect dispersal of birds from airfields
- Assist is control of nearby Vessels, without threat of using lethal force or inflicting injury
REMEMBER THIS QUESTION
In your own words explain the functioning of
centre fired rounds?
- On firing, the pin strikes the boxer type primer and crushes the anvil against the priming mixture in the primer.
- This Ignites the composition and flashes through the case hole into the cart case.
- The propellant is ignited and resultant burning produces hot expanding gases which act on the base of the projectile to drive forward through the barrel and act on case mouth forcing it outwards against breech to form a gas seal
