Different Federal Boxes
If I recall rightly, a couple years ago, Federal rebranded all of their ammunition, pistol, rifle, & shotgun.
I want to remember that they then changed packaging a couple of times in there, too.
Also, IIRC, back 8-10 years ago, the "hydra-shok" trade name got congressionally associated with the dread CKB label. As a result, I want to remember that Federal started labeling some Hydra-shoks as LE only. Naturally, that begot some labeling of "Not for LE use" too. There was some state-to-state variation, too.
There's likely an entire obsessive collector cult available in just getting all of the FCC box variations in just a given caliber. <satirical & ironic sigh>
