Anyone out there know what the story with this brass is? Other than being 9mmx19 and probably canadian all I know is that it is a PITA when de-capping and inserting primers.

I bought as 'once fired' brass. They tend to mash my primers when installing.
It almost appears as though it is sleeved? Is it ex-DND?

There's not that many to be concerned with in my current batch, I am just curious.

That ring you see around the primer is a crimp, it confirms that it is indeed once fired. Once you decap the brass you will need to remove that crimp. There are many different ways to do this. Some guys use a pocket knife, others a drill bit or dremel, there are proper hand tools and some that can be chucked up in a drill designed for this purpose as well.
 
Man, get an indoor membership someplace where they'd let you collect brass.... the membership cost often gets offset by the free brass you get over the year. Sort the brass before de-capping and toss all the undesired brass.
 
That seems like a lot of work for just a couple of pieces of brass, especially in 9.

Is it ex sub-gun? Why the particular attention to this primer as opposed to others? (ie- press fit)

Is it common? (yes, I am fairly new to loading) This stamping is the only ones I have come across after the few thou I have loaded.

It was very cheap... nbd.. The range I go to only allows collection of your own and I tend to be honest.

I mainly wanted to know the history of this brass as it is pretty obvious that it is Canadian, that is all.
 
educated guess, dominion arsenals, 1955, military loading as mentioned. Round crimp is different, and i suspect was for subgun loads in sten/stirling to retain primers on blowback. Good brass probably but not worth the effort to ream the pockets on 9mm unless your really cheap. Modern canadian crimp is 3 small crimps equally spaced around the primer
 
You better start checking your brass on a regular basis. More and more brass is popping up that is crimped, even commercial brass. Very common with NT (Non Toxic) or Lead Free ammo. Military or surplus along with Federal is crimped(FC NT headstamp) and some Winchester has surfaced with crimped primers. Primers are too precious to squish because you fail to check your brass, but if you're independantly wealthy and like the occasional BOOM if using a progressive, then continue on like you are doing now.

To get rid of primer pocket crimps, I take the deprimed case, chuck it in a drill, and use a Lee case chamfer tool to ream out the crimp. Lyman also makes primer pocket reamer tools for this purpose.

If you have a really large quantity of the stuff, it would be worth your while to buy a Dillon primer pocket swager.

A: I do check my brass carefully by hand every time
B: It was only 2 primers (so squandering the "precious supply" is not occuring)
C: I will continue on like I am doing now.

I was much more interested in the history of the brass than a few primers, there aren't enough of these buggers to bother with and they will be chucked.

The sub gun theory is what I was leaning toward..

Thanks all for the input!
