I just bought a bunch of Winchester white box 9mm Luger 115gr FMJ ammo in the 100 round "value pack". I opened a box and it has what looks like military head stamps. There is "WMA", "15" and a cross in a circle. It looks like the primer is crimped.

So is this military - NATO spec - ammo that has been repackaged? If so, that would make it +P, would it not?
 
I bought it for my soon to be here CX4 - +P ammo is not recommended for that carbine. I'll post a couple of pictures soon. All 4 boxes are the same.
 
Yet, all 9mm Nato firearms ARE chambered for 9mm Luger. Pretty much the same argument that .308 ammo will blow up your rifle chambered for 7.62 Nato.
 
Winchester seems to do that quite often. I bought a sealed box of .38 special lswc ammo a while ago that had about 50% +p head stamped cases in it. They were all loaded the same but I shot them all out of a gun rated for 357. Still not very smart on their part.
The nato marked cases I wouldn't be worried about. It was probably left over cases from a contract and loaded to normal spec.
 
I bought some AE 5.56 (in a small green plastic ammo can) that looked suspiciously like repackaged Chinese surplus.

I suspect many of the major manufacturers are doing similar things.

This would be my assumption as well. I'd shoot it. For curiosity sake though, I'd call or email Winchester about it.
 
Here they are:

Well I know I would never buy a firearm that I had to be afraid to fire + P ammo out of first of all . as for shooting that ammo out of what you just bought you should ask - call Winchester to find out if it's rated as + P or not . it looks to me like Mil Spec ammo and that would'nt upset me .

but if your going to reload that brass then you'll have to get a reaming tool to take the crimp out of the brass and that's a lousy job. time consumeing . I know there is a press of some sort for sale but I don't own one . I don't see any warnings on the box just the standard bulk box. I don't think your going to have any issues.

don't throw the brass away either .

This bugs me because I bought a set of dies at the same time. I've never done the reaming but I suspect it is a PITA.

The fact that they are 115 grain and not 147 grain tells me that they are not NATO spec rounds

I'm no expert on the matter, but STANAG 4090 states the bullet weight is to be between 108gr and 128gr inclusive. Note paragraph 4 on page 9:
