Hi
DAC Dominion Arsenal, CANADA
1944 so i would say corrosive sure someone will tell you if i am wrong, as for reloading it looks to be Berdan primed would think finding the right sized primers would be a hard task

[mgarrno4]

Thank you very much

I believe all Canadian WWII small arms ammo production was non-corrosive Boxer primed. Pull one and check for the number/style of flash holes.

Canadian cartridges, but is that boz Canadian ISAA?

It just came to me are you talking about the number of flash holes in the primer itself. not to bright today. thanks

DAC: Canadian, probably.

The primers appear to have brass cups. This would indicate that they are NOT mercuric. Commonwealth stuff with the 0.250" diameter COPPER primer cups is ALWAYS a Mercury-based primer. Mercury corrupts brass by interfering with the alloying between the copper and zinc. It has pretty much nil effect on copper on its own.

If the primer cups are 1/4" diameter, they will be Berdan style. These can sometimes be found in better gunshops. RWS 6000 is the Berdan style primer used to reload such cases. If the primers are 0.217" diameter and Berdan style, then you can use the RWS 5627, of, if you can find a stash, the RWS 5608, which is an unplated brass "MILSPEC" cup of heavier construction.

If the primers are 0.210" diameter and boxer style with the anvil in the primer cup, you are in luck, as that is a "standard" Large Rifle primer used around most of the world. Remington 9 1/2 is a classic of the breed, though just about everyone, including the Russians, makes a suitable primer.

Such primers are NON mercuric, thus the brass is less likely to become brittle after the first firing. Being "military" brass, it will probably be a little harder and thicker than "sporting" cases. See your loading manual and consult serious reloading types for more details.

Quick way to tell if it's boxer or Berdan: shine a light into the case. If there is only a central hole in the base, it will be boxer; well done. If you can just make out two tiny holes offset from the centre, it is Berdan.

There is one exception to this, as usual. There was a swag of Portuguese .303 ammo that turned up over twenty years ago. It had a large diameter BRASS cupped primer. However it had a very large anvil formed in the primer pocket. This anvil had a very small central flash-hole and a transverse slot formed in it. The final odd thing was that the primer was not the "Brit. standard" 0.250" diameter, but similar to the Russian 7.62 x 54 primer diameter of 0.254". Interestingly, 0.254" primers, like the Eley No 172 or the RWS 1775 were extensively used in British and German "Express" cartridges, like the .416 Rigby and the 9.3 x 72.

I think that's enough ammo trivia for the day.

I believe that that is not the case.....


Note headstamp, date, and presence of anvil.

Ergo, Canadian made, during ww2, Berdan primed.

Ok, I wasn't sure about the .303, that's definitely Berdan.
I am pretty sure, however, that you will find that Canadian wartime 7.92 and 9mm are both non-corrosive Boxer.

Fair enough.

The DAC .303 though is likely Berdan primed and corrosive. It is good brass and quite reloadable, IF you can get the primers...

Pulling a bullet to check the number of flash holes is a pain in a cordite loaded cartridge, in that you have to get the cordite strands out to see the flash holes - it is the very devil to get all 47-odd strands back IN again!
