72. aught notta

ezra:A Glaser in .223 would be kind of redundant since 40gr .223 already penetrates like birdshot (~1 interior wall or ~6" in gelatin). A lot of LE agencies won't even use 40-55 grain .223 JHP in SWAT use because it doesn't penetrate *enough*, instead use 62grSP..

I believe the most popular amongst ar15 owners is the 55gr, are they begging to 'be like swat' now too?

Ummm, .223 JHP penetrates *less* in drywall and typical residential exterior walls than 00 buckshot or most pistol JHP, which is a big reason why .223 carbines have replaced MP5's in SWAT use.

.. who really cares which one outperforms the other? the ar15 .223 can & does penetrate drywall & typical house walls & body armor & steel & can kill family in the next room, no doubt about it. That other self defense firearms can do so better is beside the point & a moot one as well to the point that was made - we're considering the 'most popular rifle in america', it's liability in home defense. A handgun has less chance of doing this, especially with glaser slugs.
Your shotgun with double aught is gonna have a hefty recoil if it penetrates that extent, & if you go lower recoil buck you're not gonna get such penetration. Higher recoil will make the shotgun less accurate as you try to compensate, & the ar15 might shoot 5 times more bullets in the same period gaining more 'unintentional' penetration overall. Tho the sg pellet spread might be as bad, doubt it at that range.

ezra: In tests I've seen using drywall and realistic wall spacing, typical 55gr .223 JHP will be fragmented by the time it exits the second interior wall and will be stopped in the third wall;

Which one of your kin you arguing with?: 'lalalala' 1) In a regular home-invasion scenario, it's most likely going to be a close quarter type of situation, and an AR-15 type gun would be unwieldy around corners/doorways/hallways.. the average house has a length of under 21 yards, that's still well within the range of what a handgun could handle.. handgun is also much easier to store securely in a bedroom but also have ready in a jiffy..
.. 'bear crap' wrote: ARs sucks for inside the home defense. It over penetrates through walls and its too long to handle well in a small hallway. Shotgun or handguns are better..
.. m249junky: The biggest problem with using a rifle in home defense is the velocity of the round, under stress if you miss and it goes through a wall and into your neighbors house and hits someone you are F*%#ed. A 12ga with 00 buck might not penetrate a IIIA vest but it will sure as hell knock them on their ass.
