SS192 is NOT armor piercing but FN voluntarily discontinued it in the early 2000's because of political pressure. I think they discontinued it just to appease the liberals and end a witch hunt to outlaw anything that utilizes the 5.7 round. It's just valuable because it isn't available in the US anymore. It's not necessarily any better or worse than currently available 5.7 ammo.Ok- going to go off topic here because I'm curious... I'd heard the old 5.7 ammo with a FMJ or ballistic tip was really valuable to people because it was armor defeating... why the interest in hollow points?
You can always pull bullets and replace with a HP or FMJ or whatever.
