I am not suprised.

Correct, no surprise there.

Barrier penetration is more related to kinetic energy, which increases exponentially with velocity. Thus, barrier penetration is best achieved with higher velocity projectiles.

Penetration in flesh, however, is more related to momentum, which is simply mass x velocity. This favors heavier projectiles.

If you want to penetrate body armor, RBCD may be a good choice. But, you still get a more shallow wound that may not reach the vitals.

Better bet may be the usual failure to stop drill - 2 to the chest followed by 1 to the head (aka Mozambique drill).

I don't want to penetrate body armor, if my gun were to get taken away during a struggle and used on me I want my vest to stop the round. I don't carry this ammo, I couldn't even if I wanted to. I am issued Federal HST. I ordered a few boxes a couple years ago just to see what the hype was about. I do keep a mag of it hid in my cruiser just in case I were to need such a round.
