AR-15 “overpenetration” only exists if you do THIS wrong…

 

Today, we’re going to talk about one of the biggest misconceptions that people have about the AR-15.  To be fair, they get this misconception honestly.

They’re repeated ad nauseam at gun ranges, in articles, blogs, forums, videos, and even on TV without proper context.  To complicate matters even more, there’s an element of truth to it.

What is this myth?: “I think AR’s are bad for home defense because of over penetration.  I don’t want to shoot my neighbors or kids in another part of the house.”

Good.  I don’t want you to shoot anyone who’s innocent either.

But let’s dig into this a little…

First off, penetration is good.  It gets you to vital organs and stops threats fast.  In the FBI Miami Shootout, there was a famous bullet that stopped just short of hitting the heart of one of the bad guys…it was called “the bullet that failed.”  You don’t want to use bullets designed to fail.

You’ve got to have penetration to maximize effectiveness…you just don’t want to miss your targets and have ammo go through walls into bedrooms or into your neighbor’s house.

There’s 2 components to this…

The first and most important rule to minimize innocent people getting hit in a gunfight is to hit your target with every shot.  Don’t stop training when you can hit your target…keep training until you CAN’T MISS.

That is the standard that you should set for yourself.  100% hits and no misses.  It’s not reality and there’s a really good chance that Murphy will step in and mess things up, but you want to train so that any misses you have are beyond your control…not because of a lack of training or practice.

Second, you should realistically expect ANY ammunition that’s going to have effective penetration on a person to go through drywall, sheetrock, and other wall materials if you miss your intended target..

Ordinary defensive 9mm hollow points can go through 6 layers of sheetrock or 3-4 layers of steel in a car.  There’s a good chance that ANY caliber of defensive pistol or rifle ammo has the ability to go through walls and hurt innocent people.  Hollow points that may expand when they hit soft tissue oftentimes get plugged when they go through sheetrock, don’t expand, and act like a full metal jacket round.

There are bullet designs that claim to reduce over penetration on sheetrock, and some do better than others, but regardless of how realistic it is, the best way to minimize the chances of hurting innocent people is to make your hits.

One thing that’s surprisingly consistent in penetration/overpenetration testing is that typical defensive handgun rounds penetrate MORE layers of building materials than .223 from a carbine.

But what about shotguns?  If we look at both ends of the spectrum, slugs have a serious over-penetration problem and bird shot has a serious UNDER-penetration problem.  In the middle, Buckshot shares a problem that’s common to all shotgun loads—the recoil is harder for smaller shooters to control, slows down followup shots.  In addition, the recoil and weight of a shotgun make it less enjoyable to shoot for smaller shooters and less practice translate directly to less comfort with the gun and lower performance under stress.  Finally, there are fewer ranges that allow you to practice with a shotgun than there are that allow you to practice with a pistol or AR.

Additionally, there are .22, pistol caliber, pellet, bb, and airsoft training versions of the AR…but not so much for the shotgun.

So, if all bullets are capable of penetrating through multiple walls, it stands to reason that you might want to use a weapon platform that will give you the highest probability of hitting your threat.  For most people, the increased barrel length and controllability of an AR makes it easier to hit man-sized targets at in-house distances in low light conditions under stress.

The proof is in the pudding…while nationwide hit ratios for law enforcement are in the 12%-25% range, hit ratios with rifles for many departments are over 80%.

In addition, it’s generally easier to put a light/laser on an AR than on a pistol.  There are great laser/light options for pistols, but most shooters find them easier to operate on an AR than on a pistol.

Prices on ARs have dropped to levels that would have been unbelievable a couple of years ago, and a LOT of people are buying one “just in case.”

I want to strongly encourage you to take the next step and get solid at-home training for the AR.  It will add to and reinforce any live training that you’ve had AND, if you’ve had military or law enforcement training with the M4, it’ll help you make the transition from military & law enforcement tactics to tactics that are more appropriate for a civilian.

    I keep a Taurus Judge loaded with Winchester PDX ammo in it along with a Kimber Ultra Carry II with Crimson Trace grips loaded with Hornady Critical Defense Ammo in it. Used to be a bullseye shooter and still shoot on a regular basis.

      CB,, I always knew you were a decent shot, but I never remember you deer hunting with a revolver/pistol. ( not that it would have surprised me ).

    I can speak from personal experience. My sister in law was killed by a guy she had just started dating. He used AR ( illegally owned as we later found out he was a felon). He also fired on police. he shot her 5 times from about 8 feet away as she sat in a chair. Not one round exited her body. She was hit from the left side. From the autopsy results ( yes I requested a copy and read it) the bullets did some major damage to her internal organs. Again not one exited. I don’t know what grain or type of bullets he used. I can only guess they were typical 55gr FMJ. I don’t know barrel length or twist either. If I remember correctly all of the bullets fragmented to some degree inside her body.

    The best gun (or weapon) for self & home defense is the one you’re most comfortable using and have handy when needed. If a rock is my only choice, that’s what I’ll use.

    I have to disagree about a shotgun. Too many people don’t know that there are other loads besides birdshot, slugs and buckshot. A #2 shot or BB shot will have more penetration than birdshot but lack the penetration of slugs or buckshot. In addition to full strength buckshot, there are light buckshot loads available. Everyone talks about putting enough rounds on target to put the perp down. Nobody expects to do the same with a shotgun. Why is everybody only considering one round? Two shots to the torso and one to the head. I guarantee if you have a 3/4 of an inch diameter wound in your face or head you won’t much feel like continuing any aggressive moves, especial if you already have two 3/4 inch wounds in your torso, even if they are only an inch and a half to two inches deep.

    I can remember one case where the deceased was shot at about 18 inches with birdshot from a 20 ga. The coroner said that if he had fallen on an operating table with a trauma surgical team ready to start it wouldn’t have mattered the damage was so overwhelming that no amount of medical care could have saved the individual.

    Of course, that doesn’t mean that the old saw about “You don’t have to aim a shotgun, all you have to do is point it in the direction of the perp and pull the trigger” is by any means accurate. You have to aim the shotgun just like you do any other firearm. A high base goose load, even at 2 3/4″ in #2 or BB shot will certainly take the fight out of a bad guy in short order. At household distances even with a cylinder bore the shot column doesn’t have a chance to spread much so the perp is going to get hit with a .75 caliber bullet weight close to 1,000 grains going 1200 fps. Who thinks that isn’t better than a .35 caliber bullet weighing 124 grains going about the same speed?

    A gun writer, Will Dabbs, MD, who writes for Guns Magazine did a test in the last 18 months using a shotgun with bird shot at household distances. Even at the magic 21 feet the shot column had not spread that much and it tore a vicious hole in the plywood that he was using as a backstop.

    You can do the test yourself with gallon milk bottles. Fill them up with water, back off seven yards and see how many get blasted with the shot column.

      Great points, Chuck. A shotgun is definitely better than nothing and has been used for home defense since (at least) frontier days, but two big factors for a home defense gun are how quickly you can put an accurate second shot on target (the same or different) and how easy it is to practice with. I’m not about to argue against a shotgun, but I will argue for a carbine over a shotgun in most cases…California laws may change that equation, but in a semi-free state, a carbine has a big advantage.
