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

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.

I have a puller but where are the flash holes are you talking about the primer hole. forgive my ignorance. thanks

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


Note headstamp, date, and presence of anvil.

Ergo, Canadian made, during ww2, Berdan primed.

Not the stuff that I have come across. (also DAC): Berdan primed and "corrosive" primers.

MkVIIz is nitrocellulose. MkVII is cordite. That's marked as cordite and corrosive.

Just to be clear, it's not the propellant that tends to promote corrosion but rather the primer. Nitro loaded rounds may also have "corrosive" primers.

First, as Bruce says, it is the salts in the primer that are corrosive, not the propellant itself. Both cordite and nitrocellulose are erosive over time, but in different ways.

All Canadian WW2 .303 inch ammunition made at the government Dominion Arsenal (DAC Headstamp) was Berdan primed and corrosive. Only the .303 inch made at the privately owned government contractor Defence Industries (DI headstamp) was Boxer primed and non corrosive. Most of this ammo has the "universal" headstamp of "D I Z" and date whether ball, tracer or whatever, relying on tip colour for identification.

Secondly, the ammo is not original to that box. Label H3282 is a British label from the 1950s and the ammo is 1944. Also note the label says "Mk.7" not "Mk.VII". Roman numerals were not replaced for Mark numbers until January 1945. "ISAA" is "Inspectorate Small Arms Ammunition".

Thank you all for the responses they were a great help. I know where I stand with this ammo I will enjoy and clean accordingly. All of the boxes were wrapped in in a thin plastic wrap seemed like factory wrapping, since they didn't use that box until 1945 wouldn't they put left over 1944 ammo in the boxes ?
And thanks for the reloading info on the primers I mostly use mag primers when reloading I have some Win 760 that I am using now. Sure hate to see all that good brass going to waste.
Thanks again for all the help it was outstanding in my opinion
