Armor pirecing bullets are defined in federal and most state's laws. Those laws describe a sold bullet made of a hard material or with a heavy jacket. Here in FL, the law is a bit vague and might be interpreted to include M855 green tip too. And any solid bullet made to penetrate could be a serious downrange risk. Like Ayoob said, you don't want to report "a shooting at 1st Ave and Main St. another at 2nd and Main, and at 3rd and Main".
But... Mag Safe makes a load called the "Agent" load that has the typical frangible core of shot and epoxy, but will defeat level II soft armor. No risk of overpenetration, and completely legal.
