Default Head stamp ID ???

Went to the range a while back and today I was sorting the 9mm brass and found a bunch of these. No idea what brand. Never seen this head stamp before. They are a pain to prime, almost as bad as military brass that you have to swage the primer pockets first. I was able to prime without swaging them but barely. Anyone recognize this head stamp? It looks like W M A O 2.

Probably WMA 20. That would be a military round made this year. Most likely crimped primer pocket.
Military brass has a year, commercial brass doesn't.

The Winchester ammo mfg plant in Oxford, Miss.

Don't know if WMA is:
'Winchester Military Ammunition'
or....'Winchester Mississippi Ammunition'

or neither..
Both are guesses on the ammo collectors sites.
I think the plant started US Armed Forces issue ammo production in 2015

W M A is indeed the military headstamp for Olin-Winchester's Oxford MS plant. But whether or not that is an acronym for something, I don't know.

WMA is the headstamp on Winchester's Service Grade ammo line. The "20" would indicate this batch was made in 2020.
