AR15 vs. 12 gauge shotgun for home defense

A shotgun is good but not the end all be all some would think!

I have a relative that was shot in the hand and face as a young adult, while he and some friends were playing with a loaded shotgun. He grabbed the barrel with one hand, while covering one side of his face with the other. Eye patch and some massive trauma to the arm but he is alive and well today. I don't want to think about what a .223 or 5.56X45 would have done:uhoh: ! I don't know what the load was exactly, but it was not birdshot, or slug and less than a meter and a half from his face... Draw your own conclusions.

Still 2 Many Chocies!?
 
The point vs. aiming thing has already been addressed. But I have to say, if you are not aware of how narrow the pattern is at typical household distances, you need to pattern your shotgun. You MUST AIM a shotgun (or be very very good at pointing) at househould distances because the pattern will only be a inch to a few inches. The tiny pattern is not really an advantage over a rifle.

>>Firing an AR or any high powered rifle inside your house in a urban/suburban area is just plain stupid. I'd go for a the shotgun loaded alternating 00 buck and slugs. If I had to choose a rifle it'd probably be something pistol caliber that won't go through walls and straight into your neighbors while they're sleeping.

Only if they are using FMJ in the AR. The "boxotruth" link concerns m193 ball ammo. Not HP. I assume no one--except those that are required by Uncle Sam-- would do that. 223 hollowpoints are among the best rounds in avoiding overpenetration. That's why most of the tactical units have abandoned pistol caliber smg's The overpenetration of pistol caliber bullets are exascerbated by the big and slow bullets that seem to be in vogue.

>>They're no bigger or bulkier than an AR. These are lightweight and compact and can also deliver fast, precise shots. Magazine capacity can be as many as 8-rounds. That's Mossberg 590 length-territory, without the hassle of round-by-round reloads, as well as with the added advantage of having quick, magazine-fed capability.

A CAR is handier than a short barrelled shotgun (18", folding or pistol grip) and an AR is handier than a 20" shotgun. The weight difference (shotgun far heavier) does affect the speed at which you can properly present the weapon to the target. Yes, some shotties have 9 round mags, but most have 6. All AR types weapons can hold 30 and have 30 as quickly as one put one more round in a shottie.

>>Also, even someone getting hit with 12 gauge low recoil buckshot while wearing Level IIIA armor is going to feel it regardless.

I respectfully disagree and have heard of people without armor who didn't even know they had been shot for many minutes.

>>You're already preparing for the unexpected and unlikely. Its unlikely someone breaking into your home will have armor, but its unlikely someone will break into your home. Where do you draw the line?

I have witnessed quite a few mis-strokes during "panic firing" shotgun qualifications. (Basically, empty the shotgun into the silhouette, then hot chamber, then load the tube until a whistle blows, then empty the shotgun again and repeat.) This from guys who shoot fairly often and qualify many times a year. You better practice a little in order to know how temperatmental a pump can sometimes be. We always say, "Try to break it."

>>One shot will blanket an entire door or window across the street and is the practical equivalent of an entire clip from a submachinegun.

One shot from a shotgun is more devastating than a single shot from a smg, but it isn't equivalent to short burst from a smg or AR. I've seen both a few times. Your forgetting how small and slow those little .24-.33 pellets are. The shotgun pellets don't expand at all. It's more like multiple shots from a .22.

>>IMHO, using an AR as a homedefense weapon is irresponsible unless you live alone in the middle of the woods. Overpenetration is a major concern, as well as the fact that at close range (not point-blank) an AR will poke holes in a BG who may still be able to get to you before he bleeds to death.

ONLY IF YOU ARE STUCK WITH FMJ. A .223 hp wound is devastating.

>>The target's chest would probably be shattered, but nonetheless.

False. Basic physics, the amount of energy of the slug is exactly the same as the amount that's expended into your hand or shoulder when you fire the weapon. For every action there is an equal reaction. Would placing a shotgun on your sternum and pulling the trigger shattter your chest? Of course not. A bad guy struck in a vest with a shotgun pattern won't have a crushed chest either.

>>Lee, I do believe almost any 12 gauge slug would have had the penetration to blow through the face and take out CNS.

I too have seen two different people who swallowed the barrell of a 12g shotgun and did nothing more than blow their face, nose and eyes off. Not exactly "nothing" and perhaps the bad guy would have been incapacitated, but we don't stick our barrels in the mouth of the bad guy. The pellets did not penetrate the skull or penetrate enough to cause fatal injuries (spinal cord, jugular oe carotid, etc). If your shot isn't head on, you may not incapacitate a bad guy with buckshot to the head.

The old guys or gun mag commandos like their 12g's and .45 and believe that any one shot = instant knockdown and certain death but it is simply a fairy tale spread by people who have never really been there.

Some one made the point about the sound of the pump action. Yes, people respond to racking a shotgun round, but they respond to racking an AR also.

THAT BEING SAID, my house gun is a 12g because I don't have an AR at home. Even if I did, I might leave it with the wife and keep the 12g. At work, I always choose the AR over the shotgun, but either is way better than a handgun.
 
The penetration test link provided in Post#170 (different weapons tested on four 10' spaced pieces of drywall) was quite interesting...but was rather incomplete on shotgun. Only 00 buck and #8 shot were tested...the buck went through all four walls, while the #8 birdshot didn't penetrate one. Two or three sizes in between should have also been tested. Somewhat similar tests by my Special Foces unit resulted in our choice of shotguns with #1 buck as first choice for house-to-house fighting.
 
I keep an 870 with 00 buck-once the guy hears me chamber a round I'm sure he's not staying around for the big blast.

A .729 caliber shotgun slug vastly out-penetrates any .223 loading.

Extreme case--here's a piece of "bulletproof" polycast acrylic, from the Box o'Truth:

Roberts did a bit of penetration testing there as well.

Again, .223 with JHP's penetrates no more than pistol caliber JHP's. Some from the Fackler school of thought may criticize .223 JHP's as offering insufficient gelatin penetration (often no more than 10", less for the lightest loads), but overpenetration of building materials isn't a valid criticism of them.
 
I'm in the shotgun camp. I don't care which one is longer, handier, quieter, or has more capacity.

Shooting ARs bores me to death. Pop, pop, pop, etcetera. They can't hold my interest.

Shotguns are way more fun for me to practice with. Whether shouldering up to fire slugs, swinging the barrel for some clays, or just blasting 8 rounds of reduced recoil buck into a target as fast as I can manage it, the shotties are just more fun for me to practice with and they make me go to the range, which in turn, means the BG are in bigger trouble for it at my house should they come calling.

Shoot what you like. There is no "better" in this argument, unless it is which one is better suited to one's prejudices. I like shooting shotguns so that is what I choose, and I'd still choose them if quality ARs were >$500.00 brand new.
 
cqc and bullets

I use black hills soft piont so as not to harm the neigbors, and cuz my son's in the house but yeah shotty are nice. the thing is i went through Basic and we learned how to bash peoples brians out if you get low on ammo and them4 is a nast martil arts weapon too don't discount that.
 
Just Throwing This Out There

Okay, new here, so maybe this was covered.

There are good points to both, most notably: The shotgun has ease of use and multiple contact ammunition on its side; the AR has penetration and higher capacity. (As stated before: it is important to train.)

It basically comes down to a person's own choice, the logistics of the house, and the location of the house.

There are variuous accessories that can be added to either weapon, and for home defense, I would suggest using both a lasersight and a tactical light.

Now, for the original poster, I would suggest you run drills through not only your home, but the surrounding property using both weapons. Which one is more feasible for your defensive uses? (I would look most closly at the space of your home, what obstacles exist, and which would allow you to lay down the most defensive fire in the safest way.)

On a side note, at our home we use both a long barrelled 12G Mossberg pump and a Chinese SKS carbine. (The shotgun is for clearing the house, and the SKS is to provide cover for the 'scout.')
