Mystery Round!! 9mm, identify

[lkblair]

I don not have a digital camera, but I can describe it well.

I have a cardboard box that is full of 9mm rounds.

The box says in english: 64 Cartridges
9m/m parabellum

it is about the size of a Dunhill Cigeratte pack


The headstamp bears: "DI 43 9mm"

And there is something strange on the head stamp as well.


There is a 'triangle' that 'circles' the primer. Just the tips are stamped around the headstamp, there are three tips.

I hope some one knows this ammo. My uncle who bought it somewhere says it 'submachine gun' ammo, but didnt know if it was military or what.

I pulled a bullet and it is a FMJ but has lead exposed in the bottom on the bullet.

I "Think" that it is 124 grain but I have no clue.

anyone????

What is this stuff, is it hot, where was it made, and for whom?

Help!

[chevrofreak]

From what I can gather, it is Canadian made.

[f1b32oPTic]

have you taken the calipers to it yet and compared to a luger?

[lkblair]

No, I have no cailpers.


Canada, huh? whould it be a military load It does not have any 'nato' stampings on it.


Is there any info on this somehwere on the net? Is this ammo available or is it hard to find?

I saw a box similar to what you describe at an ammo table at the last gun show. The guy said it was 9x19mm Luger made for sub-machine gun use only...but I forget who or where it was made.

[lkblair]

Do you remember a price on the amm at the show? I might not want to shoot it in my pistols, I did shoot a few rounds in my FEG PJK9HP, and I really didnt feel or notice any big differnce between the UMC 115 grain and this stuff. Muzzle flash wasnt bad nor recoil.

DI = Defence Industries Ltd., Canadian Industries Ltd, Park Avenue Plant, Montreal, Canada

43 perhaps is 1943

For a Sten? Or were they using Browning HPs then?

[Jodevilgod1]

If it says for SMG use only then its probobly a VERY hot load, for SMGs only!

[lkblair]

No, it doestn say on the box "sub gun use only, it only has the number of cartrages, and the type "9mm para". It does look like this is usbgun ammo from the North, so I thknk I will not shoot it and keep it as a curio only.


ps: When I did shooti it out of my FEG when I ahd it, it did not seem real hot, it just seemed like 'normal' 9mm ammo. I dont know, but better safe than sorry. If I cannot find it for sale anywhere, then I wont shoot up what I have.

You've got it; DI 43 is Dominion Industries, made in 1943. This ammo was made for Hi-Powers and STENs during WW2.
Edited to add: it should be 115-grain FMJ, and the "triangle" is just the peculiar style of primer crimp they were using at that time.

RESEARCH AND DEVELOPMENT DIVISION
MEMORANDUM REPORT SA-MR 20-2100

L O Spaulding/lv

24 August 1948

SUBJECT:
Effective Penetration Range of 9mm Parabellum Ammunition.

OBJECT:
To determine the greatest range at which the subject ammunition will penetrate the M1 helmet.

SUMMARY:
M1 helmets were fired at using different 9mm ammunition to determine the greatest penetration range. A Canadian 9mm Parabellum ammunition having a velocity of 1250 f/s penetrated the M1 helmet at 130 yards, which was further than any of the other ammunition tested.

REFERENCE:
Project TS2-7875-2024 J O 7875-6160

MATERIAL:

1. Weapons
a. Browning FN 9mm Pistol, HP Inglis-Canada, Serial Number 8T2367
b. Colt Automatic Pistol, Cal .45, 1911A1, Serial Number 1651407

2. Ammunition
a. Special 9mm Parabellum cases and Cal .38 S&W Special Bullets (Metal clad, 158 grains) and loaded to a velocity of 850 f/s.
b. Winchester 9mm Parabellum, 116 grain bullet, Lot WRA22026, 1,150 f/s instrumental velocity at 53 feet.
c. Cartridges, Ball, 9mm M1, 116 grain bullet (Parabellum) (Code T2CAB) Lot DIL- 617 (Canadian) 1,250 f/s instrumental velocity at 53 feet.
d. Pistol Ball Cal .45 M1911, Lot E C S25250.

3. M1 Helmets

4. Outdoor range facilities

PROCEDURE:
An M1 helmet was placed on top of a stake, back of which a target was set up to facilitate aiming and to lend support to the helmet. The 9mm Canadian pistol was then fired from a muzzle and elbow rest at the helmet. In the event the helmet was pierced, it was moved away from the shooter 10 yards and the procedure repeated until failure to pierce the helmet resulted. This procedure was followed with the special 9mm ammunition and with the high and low velocity 9mm ammunition. A similar test was run using a Colt Cal .45.

RESULTS:
1. The special 9mm Parabellum case with a Cal 38 S&W bullet penetrated the M1 helmet at 50 yards, but not 60 yards.
2. The Winchester 9mm Parabellum (1,150 f/s velocity) penetrated the M1 helmet at 120 yards, but not at 130 yards.
3. The Canadian 9mm Parabellum (1,250 f/s velocity) penetrated the M1 helmet at 130 yards, but due to lack of longer range facilities was not fired beyond this point.
4. The Cal .45 ammunition penetrated the helmet at 30 yards, but not at 35 yards.

CONCLUSION:
It is concluded that the Canadian 9mm Parabellum ammunition with the 1250 f/s velocity, had a longer range penetration power than any of the other ammunition tested.
