I recall that back around '95 there was a bunch of Fed AE Red box ammo sold that was "excess production from Desert Storm", at least that is what the store owner told me at the time. I may still have a few boxes stashed, but don't remember if the primers were crimped. I'm almost certain that back then they did not use the NATO head stamping though.
Probably easier and less costly to have a single case priming operation for both commercial and Milspec ammunition lines anyway.
There are big differences between various 55 grain fmj bullets. The latest Rem 55 fmj has a much thicker looking jacket than some older ('93?) Win 55 fmj's I compared them with.
With Fed and Win, I just can't understand why they would use one bullet in milspec ammo, and a different version for commercial offerings. Has anyone compared AE bullets to XM193?

ETA: The AE mentioned above was from '93, and came in a CAMO style carton of 500 rounds. Found an intact case! Uncrimped primers, .223 headstamp. Resealed and put back into storage.
