I remember just going to WM for Federal 9mm (nothing to do with gov’t, lol). I kept missing the immediate stocking.
I was lucky to find maybe a dozen boxes (100 rounds) over a 12 month period - across the WM’s I visited over 3 states during that time. One had a few - I went back and doubled-up after getting a box earlier that night - 24 hours and they were within 5 miles of a friend’s house (my car was at his house).
This was during king Barack, that is.
All we have to do is figure out where the storage containers are. ;-)
