I have a LOT of 45 ACP MILITARY brass. Most of it is of the Winchester (and buyout companies) headstamp.

By my own conclusions, I have found the following headstamps amoung this stuff.

WCC - Winchester Cartridge Company
WRA - Winchester Repeating Arms

I've noticed that by the date stamps on those cases that around the late sixties the Headstamps changed from WCC to WRA (around 68 I think) or maybe the other way around. All of the later stuff in the seventies and eighties seems to have the W-W headstamp.

Of course, as we all know, the newer White box ammo says "Winchester" on the headstamp.

As far as I can tell, Remington military ammo all has the R-A headstamp, followed by the date (i.e. R-A 70), the same as the Winchester cases, while the commercial cases all seem to have the R-P headstamp.

Fiocchi is the strange one, I've seen some that said "Fiocchi" and then have seen some with a "G.F.L" headstamp.

Maybe we should make a sticky with all the different headstamp nomenclature for reference?
