That looks like standard packaging for Winchester LE ammo made for American police departments (basically, in this country, a commercial sale with some exceptions. By that, I mean it is probably an LE Catalog item available to sale to any LE Agency in even relatively small amounts. It is not unusual lately for LE ammo in America to have dated headstamps, and in the case of Winchester ammunition made in the Mississippi plant, not even unusual to have the basic headstamp show, at least in 9 mm, .40, and .45, found in commercial boxes in retail gun shops.
None of that means that is can’t also be found in foreign police contracts, although I don’t know any at the moment, which again, of itself means nothing
as I can’t keep track of this stuff like I used to.
