we use a ar for home defense for the same reason you state. my wife doesnt like shotguns. there is a very good study around the net somewhere that blows the myth of 223 over penetrating out of the water. if your super worried use some of those hornady amax rounds they come in normal redtip or the zombie green tip. they pretty much disintegrate on impacting solid objects.

55gr fmj is an underpenetrator. It won't penetrate 3 sheets of sheetwall. It travels soo fast it fragments on the first wall, and the second sheet catches most of the fragments. It is super loud tho. A suppressed sbr if lawful in your state is the best tool for that application, in my humble opinion. Unfortunately, in Kommiefornia we are not allowed neither suppressor nor sbr. I live in. Townhouse with a 3 three year old. Overpenetration is a concern for me, so I have electronic ear pro and an ar pistol at the ready.

Thanks guys for all the rapid responses.
So no doubt about it getting through the brick then.
Guess I could always take some scrap Sheetrock to the range and test it for my self.
Or brick for that mater. Though that sounds kinda scary to me.

Everything else about the AR is great, practice,practice, practice.... try shooting accurately a 5 shot quick group without ear protection on and under stress.... i find firing an AR without muffs is a LOT different than with.. my accuracy on follow up shots sucks since i anticipate the hurt of the loudness...

i recommend a 9mm carbine, i can fire that all day long without ear muffs and i'm VERY accurate with it....

to each their own, use what works for her..

I'm one of those idiots who used to shoot w/o hearing protection, not anymore.

I wonder if noise would even be a factor considering the circumstances.

here ya go The Box O' Truth #14 - Rifles, Shotguns, and Walls - Page 1 these are best case tests which i think is the one we are interested in. everything goes through walls. from the looks of the 223 penetration holes ill stick with the my ar for home defense. exterior walls are much harder to penetrate than plane sheetrock.

apartment dwellers have a different scenario than home-owners. a single family home has much thicker exterior walls.

i still wouldnt use birdshot

Best Defense did a home penetration test last season. 223 was one of the best performers. I never expected that.

IIRC, buckshot and the larger pistol rounds over penetrated the most. Most of the test was the opposite of what I expected.

Same here.

Sniper, I believe one of our drill instructors was saying it had something to do with the blood actually rushing through your ears at a heightened rate due to the flow of adrenalin, the blood flow, around your brain, to help protect it (your brain). Don't quote me, it was a few years back but I think that was close to what he said, someone correct me if I'm way off base here...
