WCC w/primer pocket crimp removed = Winchester military contract.
*I* = Independance Ammo = A house-brand of ATK- CCI, Speer, Federal, Blazer Brass.
TZZ = Israeli military
CCI = CCI/Speer/Blazer/Federal, all ATK and reload pretty much identical
G.F.L. = Fiocchi, Italian
RWS = (German, Rheinisch-Westfälische Sprengstoff A.-G.)
MFS = (Fiocchi import, made in Hungary)
w-w = Winchester-Western. Same as Winchester (WIN).
Blazer = CCI Blazer Brass, which is ATK, which is also Federal & is the same as Speer in terms of reloading.
PPU = Prvi Partisan, also can be "nny", which is Serbian. Same thing as Wolf Gold.
Watch for small primer pockets, just to keep them seperated. No reason not to load small primer brass.
Why wouldn't you load them????!!??? It's 45 acp! Load them all until they split or get lost. Don't get all hung up about mixing headstamps in pistol brass. The difference is so slight you'll never notice unless you are a competition high level shooter.
The only 45 auto brass I toss without questioning is A-MERC which is American Ammunition. Junk, all of it, in 45 acp.
