US 40x53mm Grenade Cartridges


#1

I have 2 of these cases, they have the following markings:

Green anodised aluminium case:

40 MM x 53
PRAC. CARTRIDGE
IMPACT SIGN.
T
LOT NIC-96/01-02

Yellowish grey anodised aluminium case:

CRTG 40MM HEDP M440
MM-94F0P1-0004

CASE CARTRIDGE M169
ACN94D017-049

What are the manufacturers and dates of these 2 rounds? This is probably a silly question but what does HEDP stand for (High Explosive what?). The modern US aluminium cased 20mm+ stuff is [proving a nightmare to identify.


#2

the first is built by NICO in germany in 96 practice cartridge with impact marker
the second is a M 440 High Explosive Dual Purpose (HE +AP)
it is possible to have pictures about the second?


#3

I could post a photo. They are just fired cases btw.


#4

The last 2 were made in 94.


#5

This is only 2 sets of markings for 2 cartridges. I thought 94 could be the date.


#6

I’m not sure about the MM manufacturer code, but ACN on the last case is Amron Corporation.
