That box style is fairly recent. They only started using the new packaging a few months ago. BTW, I have some of that and it is excellent ammo! If you can get it at a good price, don't hesitate to buy a bunch! Even though the AE is supposed to be Federal's promo line, the pictured ammo is actually better performance-wise than the premium Federal using the same spec's.
I don't really carry a 1911 45 acp as a SD gun (just too big and heavy), however if it were ever called upon for HD the AE 230 grain ball ammo pictured is rated 890fps vs the 850fps from the regular Federal ball ammo. I don't know why, but it is faster ammo. If not using Hollow Point ammo, you are better off with the AE than other ball ammo from other manufacturers as it is actually a bit hotter. Even though I am a big proponent of hollow points for SD use, in a 1911 that was never meant to function with hollow points I opt for this ball ammo from AE. It never fails, always feeds perfectly and just plain works. I have shot tens of thousands of rounds of it.
