I'm not an expert, so my explanation will likely do more harm than good, but due to the light weight and very high velocity, the round quickly and violently dumps a lot of its energy early on and fragments. Those smaller fragments quickly loose velocity and stop. Now, don't get me wrong here, they still penetrate and are still deadly, but just not AS MUCH as some others. I know it seems backwards that a round that will penetrate a level 2 vest will also NOT over-penetrate, but surprisingly it does. I'm not suggestion you fire into the wall separating you from your child's room, by any means though!
On a side note, I saw buckshot fired from 5 to 10 feet go into a couch cushion and back of the couch and barely penetrate into the wall behind it. I also saw a 9mm (NATO FMJ) impact the wall and not exit the other side. This was fired from the interior into the interior/exterior wall.
Do me a favor here, keep an open mind, Goole search it for 75gr TAP or similar rounds, and I will dig up everything I can and post it for you. I'm not trying to change your mind on what works for you in any way, I just want you and everyone else to have all the knowledge possible on these subjects as it will help the next guy too.
A decent stock ar can be accurate up to 500 yards. A shotgun is accurate up to 60-100 yards with a standard bead site.
A 12 gauge is a great weapon, and it has tremendous stopping power, but I don't think it can be considered definitively better than an assault rifle.
I dont really care for shotguns as a home defense weapon. Only reason is I cant personally account for each of the bullets fired. My 1187 is my favorite range gun, though. :smile:
If I'm defending my home from potentially violent robbers (which is most likely), I'm probably going to grab my USP45. If somebody is hunting me down, I'll probably stay put and grab my Mossberg 500. If my house is being invaded by armored super villains or Russians, I'm grabbing my AR and fighting until I die.
It's great to have a plan. But in reality, grab what you can, fight with what you can, and what ever it is, it'll be whatever is closest and loaded. The best home defense gun for one person is different than others. There is no "best". Use what you want. Use what you need in different situations. Use what you have.
If all you have is a .38 revolver, you'll probably be just fine. If you want to use a 10.5" suppressed AR, you'll probably be just fine. Use what works for you. Like I said, I prefer my USP45 as it's quick, easy to grab, easy to get around with and I feel has plenty of power with 12+1 of .45ACP ready to go. I keep other "stuff" ready for different situations, but I'm confident that my USP45 will likely take take of 95% of any situations that would be likely to take place.
Actually during the day, if I'm just lounging around in sweatpants and a t-shirt and have no plans of leaving the house soon, I keep my j-frame in my pocket or within reach.
2. Have you ever seen an autopsy report of a person shot at close range with buck shot? I have seen more than one, and I can assure you that there is no hole you can see through. (And you tried to tell me life isn't a movie...) Yes, it does make quick a nasty wound, though. I'm currently looking at an autopsy photo from Dr. Dominick J. DiMaio who is the former chief medical examiner of New York City, in which a man was shot at "close range" in the neck with a 12 gauge, and there is quite a large and nasty entrance wound (estimating 2" diameter), but you cannot see through the victims neck.
3. You are correct about the noise difference. The report I was looking at was comparing a 26" shotgun barrel to a 16" 5.56 barrel. The 18" 12 gauge barrel is louder. However, extremely loud noise is intimidating, and it will make extra attackers think twice before running into the line of fire.
4. One well placed .22 LR in the chest will stop an attack, and I've seen it done. There's a well known video of an officer on a traffic stop who was instantly capacitated by a BG with one shot from a .22 LR. The bullet went through the armpit into the heart, and the officer was dead right there. If a .22 LR can kill in one shot, why would a 5.56x45mm round with FAR superior ballistics not be able to do so? One shot kills are highly unlikely, however, and if I'm firing one shot, there WILL be two to 29 more.
[Note: Why does my computer think "capacitated isn't a word?]
5. I agree about the shotgun being easy to use with training. However, I've never seen anyone with a shotgun fire six shots at three attackers in four seconds. (We'll say the shotgun only needs to fire three round to be fair). Sure, the shotgun is probably better in a one on one scenario, however the AR is better suited to handle multiple attackers quickly. I'll give up a SLIGHT amount of firepower in a one on one scenario, (remember that just about anyone who is professionally trained with an AR can put four or five shots to COM in two seconds), to gain an advantage in a situation where I'm normally highly disadvantaged.
6. A shotgun is designed to be "all around" good? Have you ever tried to hit anything with a shotgun at ranges over 100 yards, or even 100+ FEET for that matter? I'm not knocking the shotgun by any means as it's a tremendous CQ and hunting weapon, but it's not "all around" good.
7. You can call me foolish if you want, but I could care less. I've seen first hand what one well designed 5.56x45mm bullet can do to a person; the entrance wound may be tiny, but the damage beneath was devastating.
EDIT: Also, see here: http://ammo.ar15.com/ammo/project/select_556indoor.html
-A shotgun is reliably accurate at about 150 yards when using a decent slug. That range increases with a rifled barrel and a sabot round. But that is impractical for a purpose built defense weapon.
-The variety of ammo that can be chosen from is what makes a shotgun a better ALL AROUND weapon (like I have been saying the whole time). Again, birdshot = varmit gun, buckshot = badguys and larger game, Slug = Badguys at range and even larger game. You do not get that versatility in an AR with just a simple change of ammunition. You're swapping bolts, uppers of different calibers, etc etc etc. You can transform a 12 gauge shotgun into something that can knock a small bird out of the air, or take a small rabbit or whatever without blowing it to pieces, to a .73 caliber rifle. All by selection of ammo.
-I am not trying to convert you. This is my opinion. If I was limited to only being able to own one single weapon. I would choose a 12 gauge shotgun because of the versatility of the platform. Don't like it? I can't help you with that.
2. No I have not. I have heard stories. Perhaps they were embellished? But I have seen pictures, and you could see clean through.
4. The word you are looking for is incapacitated. And I don't disagree with anything you posted in point #4
5. Agree mostly again. A pump action shotgun is only as fast as the person wielding it. A average joe working a 12 gauge is fast enough to stop multiple attackers. If faced with multiple determined attackers I want a SAW anyway. haha!
6. If you rate "all around" goodness on range alone, then we have different definitions of "all around" goodness. :smile:
The last time I shot a man and the next time I almost did, I was extremely focused and relaxed at that very moment. This was during a carjacking with one of the carjacker's handguns. The next time (didn't fire) I had a man coming at me with a crowbar at 3am while they were trying to break into my home and I happened upon them.
Everyone is different, but I believe if you're using any weapon for defensive purposes, a lot of training and practice of that training should be fit into the schedule.
The sound of a pump shotgun is a very, very bad myth. I don't what them hearing anything if I can help it.
Well, this thread sure opened the proverbial "can of worms" !
If some BG is coming into my house, I will not be shooting from 100 yards distance. Most likely, from 10 yards distance or much less.
My 18 inch, 12 gauge Wingmaster is already chambered with a round of Number 4 buckshot; (safety on and no children in my house), and backed up by 00 buckshot.
The BG will hear a loud boom BEFORE (and if he ever does) hears the sound of the pump action.
This makes ME feel safe in my own home.
That said, this is not a fun gun to shoot; I will get out my AR or other rifles or handguns if I want to hunt or plink cans..
My Mossberg 500 is pretty fun to shoot.
The one you get to first.
