boatboy,

It's not that it won't penetrate a single layer of sheetrock. But it disrupts flight and causes the projectile to come apart to such a degree that by the time it hits the next piece of sheetrock it's ability to connect becomes tough to predict.

If you do the same test against a 9mm, 40, or 45 ACP we found the pistol rounds actually penetrated better and in a more predictable fashion.

When you add the respective projectiles impacting studs (as they would when grazing walls in a corridor) or hitting external walls the differences start to become so negligible that it becomes a moot point. Which was pretty much the point of their exercise.
