WCC & WMA 9MM Military Surplus Brass

I recently bought a large lot of 9MM at a government surplus auction (to resell) that looks like a mixture of WCC and WMA. I assumed it would have crimped primers but so far every single one that I've deprimed does not seem to have a crimp.

I tested well over 100 rounds so far and my swage gage seats just fine in the primer pockets, kind of loose like it's supposed to.

I have not tested by seating a new primer, I lost the small primer cup on my rockchucker. Once I find it or buy a new one I will prime a few rounds.

Am I wrong for assuming that all WMA and WCC 9mm brass had crimped primers? I did notice that the Nato cross was not on the brass that I've sorted though so far.

Can anyone here chime in and help me out? Do they not crimp the primers anymore?

Thanks,

Mark

Thanks for the reply. It looks like most of it is WCC 11 and WMA 12. I sorted a little more yesterday and came across some WCC with the red sealant and the NATO cross that had an obvious crimp.

My dilemma is that I bought this to resell and I don't really want to go through and deprime and swage it all if it doesn't need it (there is approx. 140,000 rounds)

Thanks for the info!
