Hollywood Gun Myths... Debunked.

Right, hence the term "AP". Typically, those are steel case / steel core bullets instead of steel case / lead core. The rounds aren't more powerful, per se, they're just "harder". They don't deform and maintain their shape better for penetration. Tungsten and similar components are also used for better AP rounds.

Concrete is a funny material and makes a poor testbed. It's non-homogeneous and brittle (generally). Much of it depends on who made and laid it. BUT, your point is well taken. The .30 cal US AP rounds can be pretty impressive.

I saw a picture of a level V vest with a hole in it from a .30 or so AP round. my guess is .308 AP but could have been any close to that size. Black tip rounds make holes, and most vests even level V I would question if they could stop more then one round of ball 30-06. It is just not a threat they were really developed to face.
