Refernces the same data set....again not really difinitive.
It has been proven time and time again that the FBI and lots of the Military's testing is flawed....lest we forget the push of the 9mm as the superior round for law enforcment and military....oddly after all the FBI testing and Army testing the choices change with more knowledge.
If you wanna defend your house with 5.56 or .223, just make sure you don't have glass in it, and that the sheet rock is packed as in the FBI experiment, ok.

There is plenty of research (including testing by Gunsite - no fan of the poodleshooter) to support that 5..56mm poses less of an overpenetration risk in urban scenarios than most pistol caliber rounds - even military 5.56mm NATO FMJ. In fact, some of the military rounds fragment quite well.
Here is a good resource for further info on that subject:
