Not up on body armor, but wouldn’t even a BTHP at 2800 FPS be more than enough to penetrate a typical Kevlar vest?

The bottom line is that most center fire rifle rounds will penetrate the level 2A vest that most LEOs wear. Any round that can be fired from a handgun other than a single shot pistol that will penetrate soft body armor can be classified as “armor piercing” and banned by an ATF “ruling.” Remember the cheap 7.62x39 steel jacket ammo that is now long gone. Also rounds can also be banned by their material construction. The M855 (SS109) were expressly exempted by law from this provision.
