Hypothetical .556/.223 Home Defence Rifle

Gunnerlove said:
IMO .223 with a good bullet and a decent velocity is safer for use in a stick framed house than 00 buck or pistol bullets. The plan is to have the bullet fragment in a sack of meat before it hits any drywall.

Look at what ERT teams are carrying, and ask why the MP5s are not being seen anymore.

But what do I know.

I couldn't agree more!

.223 all the way.
 
Good lord, the old myth that .223 will pass through drywall better than slow large bullets or buckshot is still around?

Google yourselves up some facts people. .223/5.56 fragments explosively in the softest of tissue, it ain't going through your solid drywall at lethal speeds.
 
^^ SOrry but i disagree.

The M855 (US military designation for 5.56x45) was designed with effective range of 100 to 300 yards....the bullet ballistics for needed fragmentation and induced jaw needs to slow down to just faster than destabilization. Numerous military reports of negligent discharge by soldiers at close proximity simply passing through the person with very little effect. One report goes as far as to mention that the soldier who was shot in the arm was back in action the following day. This is also the exact same reason, among others that the large military rifles of WWI and some WW2 were replaced with intermediate cartridges. They were accurate and devestating at longer ranges but urban fighting has shown that the 8x57 mausers, the 303 brits and 30/06 were not ideal for closer combat.

A 00 buck shot with 9 9mm pellets travels at approx 1200 feet. a single 22 cal. 5.56mm diameter bullet travels at over 3000 ft per second guaranteeing over penetration in close quarters. Its traveling so fast that it has no time to transfer the energy and keeps going. I'd rather see a round disperse ALL of its energy at the target.

If i had to choose home defense nr fire arm it would be a carbine chambered in 40s&w or 45 ACP. Proven defensive rounds are much easier to purchase than 5.56.

You're right.... But no one is listening.
 
Non res - Shotgun. Res - Pistol in .45

A nice bonus of the shotgun is racking the pump is a very recognizable sound and nobody wants to hang around for what follows. A non-res rifle will be way too long inside a house unless its a bullpup.
 
If you hit your target with a good .223 bullet (mk262, bear claw, ect) at close range you will have less penetration than 9mm.
If you think M855 is good ammo you need to read more.
You are more likely to miss with a pistol, and they suck for ending gunfights, accept it.
If you plan on a bunch of misses (probably on a single target) inside 20ft you need to seek out some serious training, or use a club as your primary.

The sh*t people bring up on this forum ... asking for it
 
To the guys who think i'm a mole of some sort in this thread I laugh at that. Some of these people know me and the leagues I shoot in. I've done business on this site for 7 years and owned close to 100 firearms since. I also work in the legal field (i'm not saying what). I know the law more than most people hence the framing of the question. I never said AR as an AR is restricted, I said a non restricted that takes LAR mags. Some people choose not to read.

Also, from what i've read of the ballistics of a .556 round they fragment and are as safe as a 9mm sub gun inside a home which is why some LE Agencies have been switching over. The benefit of a LAR mag is that you have 10 rounds vs how many that need to be loaded into a pump shotgun (or 5/7 depending on the mag fed design).

I framed the question as a hypothetical based on our current storage laws and what we have access to that can accept LAR mags and is non restricted. I'm not asking is self defence justifiable.

You CAN store a non-restricted in a case with loaded magazines (not inserted), bolt open, safety off and with a lock on the case. Or trigger locked but than the ammo storage question is more debatable/open to interpretation by LEOs. I'm just asking a question i'm sure someone has thought of before and many people have great and constructive advice to offer. To those people I say thank you.
