Even if it sounds counterintuitive, it's true. Defensive loads for 5.56 will not penetrate through people or sheetrock as far as most pistol rounds will.
Again, just because you haven't been correctly TRAINED to use a long gun indoors doesn't mean it's a bad idea.

You should really check that link a couple posts up! I would be happy to see another series of test results if you have a source to share though.
223 rounds tested were going through 12 sheets of 5/8" sheet-rock without stopping and twelve 3/4" thick pine boards without stopping in another test.

By contrast a shotgun is only going through 6-7 sheets of 5/8" sheet-rock until they went to slugs.

Here is an entire thread of .223 drywall penetration tests. Pretty much all of them support what mljdeckard and Steve in PA told you.

Box O' Truth gets different results because the original, early tests didn't use realistic spacing between the drywall. It takes some amount of time for .223 to yaw and fragment and it is only after it fragments that penetration begins to be reduced. In the original BOT tests, the drywall sheets are spaced so closely together that .223 exits before that can happen - note that the yaw doesn't even start until the 6th of 12 sheets in that test. BOT #1 also doesn't indicate what portion of the bullet exited or how much remaining energy the bullet had, which can lead to erroneous conclusions.
Now take a look at the tests linked above and see what happens when you have a more realistic spacing between interior walls.
I guess those test results show off particular bullets pretty well when fired (mostly) from a SBR at a range of 21 feet? Some cool tests to be sure and definitely shows that certain projectiles will fragment quickly, they also show that others will not. For the most part it looks like most 223's when fired through a single wall will still give lethal penetration according to Federal's own tests. I use a handgun for home defense myself because it's quick and easy to handle and I have no urge to run around my house like Rambo with my AR, I'm pretty sure my coffee table would break if I tried to do a tacticool roll over it anyway.
I'll admit that certain 223 rounds have been proven by these tests to be safer for bystanders than many pistol rounds while others haven't. I do like how 230grain shoots at closer range making it a much more realistic test. My only complaint with his methodology was using the same pieces of sheet-rock for all testing.

Yeah, two 5/8" sheets of drywall aren't much of a barrier when it comes to stopping bullets. There is a long list of ammo that has the potential to be lethal after going through a single interior wall.
But let's say you could have a magic round that would stop instantly in a single interior wall; and would still be very effective if it hit an attacker. Would you be willing to use such a round in your house knowing that almost everything in your house was now hard cover for your ammo; but that there was a better than 99% chance that your intruder could shoot through many of those same obstacles?
Well, I don't have any urge to run around my house like Rambo - especially if I think I need a firearm seriously; but I do want to hit what I shoot at and fire as few shots as possible and an AR beats a pistol in terms of accuracy and terminal effect.

I said DEFENSIVE loads. No one is saying to take G.I. SS-109 ammo and load it up to shoot in the house.
