[Study] Home Defense Overpenetration: Shotgun, Handgun, Rifle

Over-penetration in a home defense situation can cause more harm than the original threat.

If, God forbid, someone should break into your home, you will have a million thoughts racing through your head, and a stress level some people may never feel in their life. 

My .300 Blackout HD Pistol

While you are nice and safe reading this article, this is EXACTLY the time to think about over-penetration and the liability that comes with it.

In this article, I will be discussing over-penetration with 12-gauge shotgun loads, 9mm and .45 ACP handguns, and finally 5.56 NATO/.223, and .300 BLK AR-15s. 

Less than 1/5th of the ammo I tested. Buckle up.

This is not a test of the firearms, but rather a test of what the firearms are shooting.

Assuming you are looking at roughly the same barrel lengths, the exact firearm using these cartridges will be approximately the same.

Penetration testing was done these loads through real, current building materials, and I will cover the pros and cons of each caliber/load and how they performed in testing.

This is a long article, but it’s important and worth the full read.

We’re going to dispel some fudd lore and provide real data to help you make the best decision for your family in your home.

The Setup

To simulate a real home, I made 2’x2’ frames with 2″x4″ studs and then sheeted them with 3/8″ drywall on each side to simulate an interior wall.

I also built a simulated exterior wall by framing a 2’x4′ wall sheeted in 3/8″ drywall and 1/2″ plywood on the exterior side. Inside of the exterior wall, R13 insulation was added for added realism.

Author’s set up, simulating an “intruder” with an interior and exterior wall panel behind the target.

A card table was placed with a 12″ long 10% ballistic gel block 12 inches in front of the interior wall panel.

This 12″ of ballistic gel is used to simulate an intruder’s chest cavity. The gel was calibrated per FBI specs for 10% ballistic gel and can be found at Clear Ballistics.

Ten feet behind the interior wall, the exterior wall was placed. All shots were taken 10 feet away from the 12″ ballistic gel “torso”.

If a round made it through the gel and both walls, it failed the test for over-penetration. A “clean miss” was also shot with every load to test over-penetration when the shot did not encounter the ballistic gel block.

Here’s a hint. Don’t miss.

Soft tissue does a heck of a great job with slowing down projectiles and destabilizing them for potential fracturing. Every load with exception of the #9 Birdshot, blew through both walls and “exited the house” when there was a clean miss.

Disclaimer

I understand that all homes are different, so before people start chiming in what their home is made of, I think my choices show current common materials that are used in the manner they are most often employed.

You may have brick, cinderblock, plaster and lathe, or have open floor plans in your Scrooge McDuck mansion. My setup would be more typical for smaller single-family homes.

If this is your home, you might want to look into something in belt-fed so that you can cover the front yard.

It should also be pointed out that ballistic gel does not represent a human well, it has no bone, fat layer, clothing, or muscle.

All of these are somewhat different for each person, and exact shot placement will also matter, so real-world results will have a degree of variation to them that we cannot replicate.

The point of the gel is to give a consistent medium that is dense enough yet soft enough to effectively test munitions. The primary goal is standardization, not perfect replication.

Gel is also fun. FYI, .44 Magnum will mess you and your gel up!

Results will also have slight differences depending on the firearm you use. But it shouldn’t be hugely different. The design and overall specs of a cartridge are more important.

Lastly, please actually read to the end of the article before you start writing your dissertation on why you think I’m wrong.

And remember that I actually tested all of this, have you?

EDITOR’S NOTE: Please forgive the parts where Ken reiterates himself, we wanted to make sure that if you the reader only jump to one section to read the results, you would have the critical information needed. As such, we describe in short the set-up and testing multiple times.

With that out of the way, time for the fun stuff!

Shotgun Over-Penetration Testing

The Shotgun And The Shells

The shotgun that I had for testing was supplied by Remington Arms. It is their 870 DM Predator with an 18″ barrel in a Highlander Kryptek finish. It has a thumbhole stock and utilizes a 3 round or 6 round detachable magazines.

Cycling has been reliable, and I have really enjoyed the shotgun while hunting, or running defensive drills with it. It also has proven itself to me from multiple hunts with hogs, turkeys, and coyotes.

Not one hiccup, so for me, it has been my choice for home-defense.

Mounted on top is an AT3 Tactical RD50 micro red dot sight. Zero has always stayed locked on, and the mini red dot has performed flawlessly. I tested 4 different loads ranging from the whole spectrum of shotshells.

Remington 2 3/4″ #9 Target Loads – PASS… KIND OF

I wanted to test birdshot first to clear up some possible misconceptions. A lot of people who worry about over-penetration consider low brass, birdshot loads to be a perfect choice for home defense. This is a bit of a gray area in my opinion.

Lethality has been proven to be less than desirable and fluctuate depending on the range to the target.

12ga Birdshot, Opened
12ga Birdshot, Opened

While I don’t think you will ever meet someone that would want to be hit by birdshot within 20 feet, lethality is an important topic.

If someone is actively trying to take your life, a load needs to have adequate penetration to reach vital organs.

While this load did not over-penetrate after it hit 12″ of ballistic gel, on a real human target with fat, dense muscle tissue, and a rib cage, it may not get the job done due to small shot size and shot deformation.

I give these loads a passing grade, but only as a LAST OPTION.

There are MUCH better loads for lethality.

Remington 2 3/4″ 00 Buck – FAIL

00 Buck has always been a popular option, but the problem is that most people do not consider over-penetration. While it has devastating terminal ballistics, the dense and fast-flying .33 caliber pellets do not stop after encountering soft tissue.

Testing these loads proved that after encountering 12″ of 10% ballistic gel, the pellets continued through the first interior wall and easily passed through the exterior wall.

HD overpen test buckshot exterior wall
00 Buck can be a viable option, but over-penetration can be a liability.

Since this test deals specifically with over-penetration, 00 Buck gets a failing grade for home defense.

Terminal ballistics would be devastating, but like a freight train, they weren’t deterred by flimsy drywall or 1/2″ thick plywood panels after exiting.

Barnes 2 3/4″ Expander Slug – FAIL

Loading the Barnes Expander slugs into the 870 DM’s magazine I hoped for the best.

I thought that there could possibly be a chance that due to their design, the slug would have enough rapid expansion that they could slow enough to not punch through both interior and exterior walls. 

All hopes were shattered after my first shot. Once again, the slug pile-drive through a fresh 12″ of 10% ballistic gel without a hiccup and sliced through each wall with little effort.

HD overpen test slug ex wall
The Barnes Expander did not have enough expansion to prevent over-penetration. Even on this exterior wall, it was almost totally unexpanded.

The velocity and the mass of the slugs create a deadly mix of incredibly high muzzle energy, which translates into serious over-penetration through barriers.

I wouldn’t think twice about using this slug in a hunting scenario but for a home defense load, almost any slug will likely leave your home and fail.

Federal Premium 2 3/4″#4 Buck – PASS

After witnessing the last loads fail the test, I didn’t have much hope anymore that a shotgun load in 12 gauge could meet requirements of deadly lethality, and not blow through multiple walls and exit a simulated home.

Hope soon returned to me though after firing Federal Premium’s #4 Buck out of the Remington 870 DM Predator.

 This load is loved by many coyote hunters because the pattern and range work well, and the size of the pellets perform well on soft tissue.

With most of the 29 pellets either lodging themselves within the 12” gel block or being stuck within the interior wall, this type of load is in the “goldilocks zone” of terminal ballistics and lacks severe over-penetration like 00-Buck.

Firing into the 12″ ballistic block, it was apparent that not all the .24 caliber pellets passed through the first wall. Upon visual inspection, some of the pellets stayed within the 12″ of gel, while some were planted into the first sheet of drywall.

Best 12 Gauge Home Defense Loads

Based on this testing, only one shotgun load is really good enough to recommend, but shotgun loads are more acceptable as a class than other ammo types – so here is a couple of options for #4 Buck you might want to look at.

1. Federal Premium 2 3/4″ #4 Buck

As our testing shows, Federal Premium #4 buck is a solid choice that delivers on every front in a shotgun load. We trust it.

2. Federal Power Shok 2 3/4″ #4 Buck

Power Shok has been around a long time and is a common load for deer, hog, and more. If it works on 4-legs, it works on 2. It is a bit more velocity than the Federal Premium, so if you have thin walls keep this in mind.

Pros and Cons for The Shotgun

The 12-gauge shotgun is a proven weapon that has been fielded by the military, law enforcement, and millions of Americans out in the field while hunting.

It is a formidable weapon that has impeccable power within short to moderate range, depending on the load being used.

12ga Shotgun Shells, Opened (L to R: Bird, Buck, Slug)
12ga Shotgun Shells, Opened (L to R: Bird, Buck, Slug)

Multiple loads are one of the biggest advantages to the shotgun since a shooter can have a very diverse choice between birdshot, buckshot, slugs, and honestly even less-than-lethal offerings with bean bag or rubber shot loads.

The shotgun is highly adaptive, and there is no wonder why some people would choose it for self-defense in the home.

Gun Bed!
Gun Bed!

It would seem odd to consider power being a detriment to home defense with a firearm, but a 12-gauge shotgun must be wielded responsibly.

A higher level of recoil should be considered as well as over-penetration. #4 Buckshot is really the only load that I would recommend in a home defense situation.

When you also consider magazine capacity, and the substantial recoil of the 12-gauge compared to a carbine or short-barreled AR15, the cons add up quickly.

With any weapon, train with it to minimize any user error issues that are common with the pump shotgun like short-stroking.

With regards to over-penetration though, the more lethal loads must be used responsibly, and you need to know your home. Keep in mind, 10% ballistic gel is still not a human being.

This is the most scientific way to replicate a home intruder shooting, and YMMV.

Final Shotgun Grade

Terminal Ballistics – 5/5

Depending on the load, the shotgun is an absolute powerhouse when it comes to terminal ballistics, shock, and awe. But keep in mind, you need to use the proper ammunition if over-penetration is a concern with you.

Wound Channels – 4/5

A slug is a game-ender, but when it comes to better loads for home defense the #4 Buck is still a solid performer.

#9 Birdshot, if it is the only thing available, is not a horrible option in terms of over-penetration, but it must be understood that it will not be effective on soft tissue unless the range to target is within a few feet.

Over-Penetration – 2/5

Overall, the 12-gauge shotgun has either way too much over-penetration or lacks terminal performance in birdshot loads.

The goldilocks shell is the #4 Buck loads that were tested. If your trusty scattergun is loaded with #4 Buck, there are worse ideas with protecting your home and family.

Recoil Management – 3/5

With training and blood sacrifices to Jerry Miculek, anything is possible. The shotgun can be harnessed with enough time behind it, but it is still much stouter than a typical defensive carbine or handgun.

Overall for Home Defense – 3.5/5

The shotgun is a powerhouse and at close range, it can be an absolute game-changer, but it must be used with the correct ammunition to avoid over-penetration. Recoil is something to be aware of if follow up shots are needed in quick order. Magazine capacity is limited and reloads must be practiced to be efficient.

Handgun Over-Penetration Testing

Between home defense, and self-defense outside of the home, the handgun can be a great choice to protect yourself.

Or is it?

The set-up is the same for the shotgun, 12” 10% ballistic gel block that is calibrated to the FBI’s specifications.

Behind the ballistic gel, I placed a simulated interior wall built of common construction materials. Ten feet behind the interior wall, I placed a larger exterior wall composed of 2”x4” studs, 3/8” drywall sheeting, R13 insulation, and ½” plywood.

The setup during construction

Calibers that were tested included the 9x19mm, and the venerable .45 ACP.

How did they stack up?

Let’s find out if pistol calibers tear through soft tissue and drywall like a wet tissue.

The Handguns and Ammo

With this test, I chose 2 common handgun calibers for better experimental accuracy. Striker-fired, semi-automatics were chosen due to their popularity.

For the 9x19mm, a Polymer 80 PF940Cv1 80% frame was used that was sent to me by JSD Supply. They supplied the barrel, frame and all the part kits associated with a Glock 19 build. The PATMOS barrel has proven to be very accurate.

I can’t speak highly enough on the Trijicon RMR. At this point, if you are building a Glock slide, don’t think twice. Get the RMR cut and plant an RMR on it. It’s a beautiful marriage of looks and functionality.

For the .45 ACP, my personal Glock 36 was used. This model uses a single stack, six-round magazine and is purpose-built to be a small yet powerful conceal carry handgun.

It has been highly reliable and further cement Glock’s reputation in my opinion. It is still a complete factory set up, and nothing has been changed since I bought it years ago.

Ammo supplied for testing came from Remington, Hornady, Federal, Inceptor, and Lehigh Defense.

All ammunition was tested with a “clear miss” shot. Not surprisingly, every round that missed the 12” of 10% ballistic gel passed through both walls and out of the “house”.

Best 9mm Home Defense Loads:

Both loads worked great from Federal Premium, which is why I grouped them together.

Both showed great expansion, and after passing through 12” of ballistic gel, the first interior wall was able to stop the expanded slugs.

While the 135-grain Hydra-Shok Deep did penetrate further, the slug was found on the ground right behind the interior wall.

Side by side, the Hydra-Shok Tactical (left), and Hydra-Shok Deep (right).

Either of these rounds would be excellent choices for home defense where over-penetration could be a concern, and it shouldn’t be a surprise.

Federal Premium’s pedigree with quality ammunition is well known.

Where the Hydra-Shok Deep penetrated more, it is by design, where barriers may be a concern with carrying for defense.

2. Lehigh Defense 105-grain Maximum Expansion

The Lehigh Defense Maximum Expansion line is something to truly behold for self-defense. It truly lives up to its name of Maximum Expansion.

Lehigh Defense 105-grain Maximum Expansion 9mm

I tested this ammunition a few times to make sure that there wasn’t a fluke. Each time, penetration was 10.5” inside of the 12” of ballistic gel and expansion was predictable. 

Lehigh Defense 45 ACP and 9mm

While exit wounds cause more trauma, and allow more hemorrhaging, all kinetic energy would be dumped into a target using the Maximum Expansion bullet from Lehigh Defense. 

3. Hornady 124-grain Critical Defense

Hornady Critical Defense didn’t disappoint.

After passing through the 12” of gel, the expanded slug impacted the interior wall and passed only through the first sheet of 3/8” drywall.

After removing the sheet of drywall, I found the slug resting on the bottom 2×4 plate of the simulated wall. 

With the flex tip unrecoverable, the recovered slug of the Hornady Critical Defense 9mm

It was still hot as well!

The expansion was not quite as large as the Federal Premium, or the Lehigh Defense, but in terms of over-penetration, this round performed great.

If expansion is more important in your opinion, the Federal or Lehigh Defense option would be a better choice.

Best .45 ACP Home Defense Loads:

1. Federal Premium 230-grain Hydra-Shok Tactical

Just like the 9mm, the bigger brother in .45 ACP performed amazingly. Expansion was even more significant with the larger bullet.

The bullet, after penetrating 12” of gel, was stopped by the first interior wall and was found lying on the ground. Expansion was large, and the wound channel was impressive after cutting open the block later.

Federal HST .45 ACP (left) and HST 9mm (right). Both expanded perfectly with near 100% mass retention.

Federal Premium’s widely known Hydra-Shok bullet is something of a gold standard to judge other bullets. You can not go wrong with them.

2. Lehigh Defense 174-grain Maximum Expansion

The Maximum Expansion in .45 ACP was surprising. After firing, it was obvious that the bullet did not penetrate out of the 12” of ballistic gel.

Lehigh Defense 174-grain Maximum Expansion .45 ACP

Cutting open the block revealed that 10.5” of penetration was achieved, but the expansion was what was even more notable. The .45 caliber projectile opened to double its size with four large, sharp, copper petals.

Lehigh Defense 45 ACP and 9mm

3. Remington 230-grain Black Belt

The new addition to the Remington line-up in the Black Belt performed well.

Expansion wasn’t as large as the previously mentioned bullets, and the slug came to a rest in the second wall. For this test though, the ammunition proved to be a solid performer with a balanced level of expansion and penetration.

Recovered Black Belt slug for the .45 ACP from Remington.

This bullet has been tested in defensive situations including auto glass, wood, and heavy clothing where extra penetration is needed to get the job done by the FBI.

It is purposely designed to be a jack of all trades, and in my testing, it proved a viable option for home defense.

Pros and Cons for The Handgun

The handgun is an extremely popular firearm.

Many people who carry a handgun day-to-day will naturally gravitate towards this firearm for home defense.

A handgun is a compact, light firearm that is a good choice for home defense, but it does have its weaknesses.

A lot of options when it comes to handguns…

Projectiles for a handgun are large, short, and heavy by nature. With a clean miss, slugs tend to keep barreling through barriers.

But, a properly designed self-defense bullet has shown to be suitable for home defense when the projectile encounters soft tissue in my testing. 

In a high-stress situation like a home invasion, acquiring your sights in low light may be problematic. While a red dot mounted on the slide of a handgun is a quick way to get on target, keeping rounds on target can still be a challenge when your heart rate is off the charts.

Tested Pistol Red Dots
Some of the Best Pistol Red Dots we’ve tested!

Not having a stock planted in your shoulder is a major drawback in an accurate volume of fire. 

Terminal ballistics are also not comparable to a rifle cartridge either. Law enforcement and self-defense shootings show that multiple rounds are needed to incapacitate someone in a defensive situation.

Shot placement is key with a handgun so regular training behind a handgun is important.

Final Handgun Grade

Kinetic Energy: 3/5

Regardless if you shoot the baby 9mm, or your 1911 won back to back World Wars, kinetic energy is lacking compared to the shotgun and rifle. It will get the job done, but shot placement is key.

Wound Channels: 3.5/5

Velocity levels are relatively low in most pistol cartridges, so wound channels and temporary wound channels tend to be less than a centerfire rifle. The larger a projectile expands though, the more damage a slug can do.

Over-Penetration: 4/5

While it should be widely known that FMJs over-penetrate soft tissue, quality self-defense ammunition slows quickly due to rapid expansion.

A clean miss is going to blow through multiple walls without issue, but if you make the hit count, it is going to stop within the target or stay in the first wall it encounters.

Recoil Management: 4/5

Recoil in most common defensive cartridges is manageable. It does require training, and proper grip though. An AR in a PCC would make recoil much more manageable for home defense.

Overall for Home Defense: 3.5/5

In the right hands, and with the right load, a handgun can be a viable weapon to defend your home with. I can’t stress enough that training needs to happen in preparation.

Shooting under stress with a handgun can be difficult, and if you need to defend yourself, you need to make the hits count.

Rifle Over-Penetration Testing

Some people are highly skeptical of a rifle, specifically the AR-15, for home defense. Some consider it a bad fit for home defense, due to over-penetration.

To find out, I went about setting up a test just like the shotgun and handgun. It involves shooting a 12” 10% ballistic gel block that is calibrated to FBI specifications. 

Behind the ballistic gel, I placed a simulated interior wall used of common construction materials.

Author’s set up, simulating an “intruder” with an interior and exterior wall panel behind the target.

Ten feet behind the interior wall, I placed a larger exterior wall composed of 2”x4” studs, 3/8” drywall sheeting, R13 insulation, and ½” plywood. Calibers tested include 5.56 NATO/.223 Remington, and the .300 Blackout.

Is the AR15 the best defensive weapon for your home?

Or are you at risk of shooting your neighbor’s neighbor? Does it over-penetrate like a railgun from Eraser with Arnold Schwarzenegger?

The Rifles and Ammo

For the 5.56 NATO, the rifle I used in testing was a Bushmaster Minimalist.

With its mil-spec receivers, 16” nitride barrel, proprietary “tear-drop” free-floated handguard, and lightweight Mission First Tactical Minimalist stock, it made a great test rifle to use for home defense.

The .300 Blackout is my personal AR15 pistol that I built. It uses an 8.2” Rosco Manufacturing nitride barrel, a BCM MCMR 8” handguard, Toolcraft BCG, and an SBA3 pistol brace sent to me by SB Tactical.

This bullet did very well for a standard soft-point, but weight retention did suffer. One test shot barely indented the first sheet of drywall.

3. Inceptor 35-grain Frangible

This frangible option with Inceptor is a relatively new design of bullet. It is made of a polymer and copper matrix.

It is designed to disintegrate upon striking anything harder than itself. It did not over-penetrate through the simulated walls of the “house” though even though some shots fragmented more than others, probably depending on how it tumbled through the first wall.

After encountering soft tissue, the Inceptor 35-grain bullet tumbled violently.

When firing a “clean miss”, this load was the only cartridge that did not over-penetrate, although it did hit a stud. A copper-colored dust cloud was all that remained on the other side of the interior wall.

Another “clean miss” shot was done and missing a 2×4 stud the bullet passed through both walls.

Wound channels were not as great as the other options, but for the sake of this experiment, this frangible bullet did very well.

Best .300 Black Out Home Defense Loads:

1. Barnes 110-grain VOR-TX TAC-TX

This Barnes load is maximized for the .300 Blackout, and it was the top contender for this caliber. Expansion proved to be reliable, and penetration ended in the first wall after passing through the 12” of ballistic gel.

Say what you want, that’s a big bullet getting stopped by dry wall. Awesome display of how much energy it dumped into the gel block!

With a whopping 1350 ft. lbs. of kinetic energy at the muzzle, and the amount of expansion, the terminal ballistics on this load are impressive.

I can not recommend this load highly enough, and it exceeded expectations from a rifle cartridge for home defense.

Amazing performance from Barnes Vor-Tx 110gr .300 Blk

Not only that, but literally ANY .300 BLK barrel has shot this load with insane precision. For hunting, or for home defense, Barnes would be my top choice.

2. Lehigh Defense 115-grain Controlled Chaos

Where the 62-grain .223 load failed, the 115-grain .300 BLK load pulled through. Both bullets expanded and had great terminal ballistics, but the base of the .223 over-penetrated through both walls.

The fragmented petals of the Lehigh Defense 115-grain Controlled Chaos

The .300 BLK expanded and then fragmented within the first 6” of gel. 

These petals caused secondary wound channels that stayed within the 12” of gel. The base of the projectile passed through the interior wall but ended its travel within the exterior wall.

Even though the petals are unpredictable, they will wreck soft tissue.

3. Inceptor 88-grain Frangible

Just like the 35-grain .223 Remington load from Inceptor, the .300 BLK did not have amazing terminal ballistics inside of the gel.

This isn’t surprising since it essentially has the profile of an FMJ projectile. The projectile destabilized very well though.

Regarding over-penetration, the Inceptor performed well and shotgunned into multiple fragments after exiting the interior wall.

At 1270 ft. lbs. of energy at the muzzle, this load would cause substantial damage.

Pros and Cons for The Rifle

Where the handgun comes up short with kinetic energy, and terminal ballistics, the rifle takes the lead. Due to the much faster velocities capable with a rifle cartridge, terminal ballistics are substantially more devastating than a typical handgun cartridge.

Furthermore, stability with a stock or pistol brace under stress is much easier than a handgun.

Then again, jeans worked for Keanu...
A stock helps. A lot. But training helps more!

While the shotgun has impressive terminal ballistics, it takes proper training to stay on target and mitigate recoil. Between a 5.56 NATO or a .300 Blackout, recoil levels aren’t in the same class as the shotgun and require less training to be proficient.

Given the proper ammunition selection, the rifle also has less over-penetration than the 12-gauge shotgun.

There are drawbacks to using a rifle cartridge though. Using a typical AR-15 with a muzzle device will produce eardrum piercing and disorienting concussive blasts in smaller rooms and hallways with no hearing protection.

This can be dropped to safer levels with a suppressor but could be cost-prohibitive to a lot of people.

Also, most carbine length ARs are substantially longer than a handgun and require training to properly navigate around corners and around obstacles.

Final Rifle Grade

Kinetic Energy: 5/5

Kinetic Energy is off the charts with centerfire cartridges compared to the handgun. To get the full advantage of the kinetic energy on target, proper ammunition must be used.

Wound Channels: 4.5/5

Wound channels, especially temporary wound channels, are also much more devastating compared to the handgun, or even some shotgun defensive loads. The high velocity of centerfire cartridges, especially in 5.56 NATO are the reason for this.

Over-Penetration: 4/5

Clean misses still have major over-penetration, but the projectiles destabilize much more quickly and lose energy compared to the handgun and shotgun. Especially with 5.56 NATO, due to its long and thin profile.

Recoil Management: 5/5

Recoil management, whether in 5.56 NATO or .300 BLK is some of the easiest to deal with. Using a stock, or a pistol brace helps stabilize the weapon in the shoulder, and fast follow up shots are a breeze without much training behind a weapon.

Overall for Home Defense: 4.5/5

The SBR/Pistol or carbine sized AR15 is one of the absolute best defensive weapons to have at your disposal for home defense.

While there are cons to the platform, especially with the muzzle report in smaller rooms, overall for performance the AR15 is hard to beat in comparison with the handgun or shotgun.

    My big surprise was that the 00 buck was going to get me in trouble. My carry/house gun is a ruger Officer model in 9MM with 9+1 and a 10 reload and it comes off my belt and into a holster on the bed frame. I think of the Rem 1100 shotty as the gun I'll go to if there is time, or if the zombies are coming down the street but the gun that will be in my hand with only a second or two warning will be the 1911 Officer. I've probably got close to 100K rounds through my big .45ACP 1911's so the platform is what I'm most comfortable with. All of this is with the understanding that I've taken all the compromises and odds into consideration and shoot 150 to 200 rounds a week in practices and matches. Thanks for the good work.

    Good concept and article. It obviously took a lot of work. As a community we've reached a pretty solid consensus with regard to the most effective ammunition, but that was just the first step. Now we're going to the next step and considering over-penetration and the safety of bystanders. I'm waiting patiently for the third step - an article that considers the safety of my ears when firing inside my house. I'd guess the best would be the 300 Blackout, but I'm looking forward to not having to guess.

    Really nice job on this test and article - thank you. You mentioned the dangerous noise levels surrounding use of a rifle in an enclosed space, which is absolutely true. To that end, one of the big advantages of the 300 BLK round is that it can had in subsonic bullet weights - add in a suppressor and you're good to go. As I just built my very first AR pistol, I admit to being a bit disappointed you didn't test at least one subsonic load in this caliber.

    1 week ago
    • Ken Whitmore

      Keep in mind the limitations of subsonic loads in .300 BLK. While it's great suppressed, it neuters the cartridge for terminal ballistics. By all means, it is still adequate for defensive use, but the terminal ballistics mimic more of a pistol cartridge due to the velocity drop keeping it subsonic. Not trying to persuade you either way. Just something to think about and to know! Thanks for reading my article!

    Great Article, thank you for your time. How does the 20 gauge stand up for home defense? I want to get a home defense shotgun, but I know my wife will not handle the recoil of the 12. Thanks Dan

    1 week ago
    • David, PPT Editor

      20ga is perfectly suitable for HD! Generally, the performance of a shell will not change much based on gauge. Federal Premium #4 buck in .410, #4 buck in 20ga, and #4 buck in 12ga are all rated at 1,100 FPS. They will all have basically the same penetration and terminal effect on target. The difference is how much shot each actually carries. #4 buck in .410 only has 9 pellets, 20ga has 24 pellets, and 12ga has 34 pellets. Since it is a shotgun more shot means a denser pattern, but this can be alleviated a bit with the use of a good choke. Also, since this is for HD and the range is likely going to be on the short side then pattern density shouldn't be too much of a concern. Granted, more shot is always better for putting down a bad guy -- overkill is underrated. But if a weapon is unmanageable, then downsizing to something that is manageable is critical.

      I did a few tests trying to figure out how I wanted to test the medium I was shooting into. I even tested 10" of gel wrapped on either side by pork ribs, covered in a shirt. I tested the Remington Ultimate Defense with that. Same results. Either the bullet was "trapped" in the back shirt, or it indented the first sheet of drywall. Basically the same outcome. For repeatability, I stuck with 12" of gel for the entire testing.

    Talking about 12gauge birdshot the article says: "While this load did not over-penetrate after it hit 12″ of ballistic gel, on a real human target with fat, dense muscle tissue, and a rib cage, it may not get the job done due to small shot size and shot deformation." I realize that this article was designed to semi-scientifically test "over penetration" and that lethality wasn't examined in detail, but there is no need to guess about "may or may not get the job done" when others have done equally semi-scientific testing on the lethality of birdshot at practical home defense distances. Of course there are others, but I think most would grant that Paul Harrell's approach is closer to realistic rather than shooting at wood stakes or even ballistic gelatin. You are absolutely correct that birdshot is highly range-dependent, so it is important to consider realistic "home defense" distances, and also important to recognize that realistic distances can vary greatly depending on both the home being defended and the defense strategy chosen by the defender. As an instructor, I was limited to teaching the state-mandated curriculum, which did not address home defense strategy; but when questions on that topic did come up I was generally a strong advocate of the Ensconced Defender strategy and always discouraged a "defender" going looking for any intruders.

    This is a great article, but for those interested in playing with wheel guns, there is another web-article at Lucky Gunner from about three years ago that gives comparatives on .38 and .357 loads expressing velocity, penetration, and expansion for each bullet for the 2 inch and 4 inch bbls employed in the tests. Fascinating interactive data tables there will allow perusal to find something that suits the revolver in your drawer. Of course, similar statement: Read the entire article so you know what the author did in establishing his test parameters and what the results MAY mean in real world conditions.

      With a PCC, velocity would have been higher, but overall the effects would still be relatively the same for expansion and penetration. Handling would obviously be different and would share the same pros as a centerfire rifle. Regardless though, it would still not have the same terminal ballistics as the rifle cartridge.

    Anything that did not pass through the 12 inches of gel should not be considered a viable defense load. There is a reason that the FBI considers 12 inches as the minimum acceptable penetration depth for defensive ammunition. If it didn't pass through the gel and the wall it would not likely pass the FBI protocols.

    1 week ago

      A better test would have been 15 inches of gel with a minimum of one layer of cotton front and back. Ideally the round should still penetrate completely through and punch through at least one layer of 1/2 inch drywall.

    Although I think you guys did a tremendous job in your testing (very thorough & enough variance in ammunition), I just want to add a couple of comments. To get closer to "real world" results out of the ballistic gel, possibly consider adding a layer of material to the front & back of the gel to simulate average clothing? Wall construction FYI. I am in the construction business in Virginia. Other regions may have different standards, but here 5/8" drywall & 3/4" plywood are typically used for exterior walls. Interior wall construction can vary depending on the "cheapness" of the owner/contractor but I have never seen something as thin as 3/8" drywall used. Just my 2 cents worth but you guys did a very scientific test. Thank you!

    • Ken Whitmore

      I am not a carpenter by trade, but I figured my choices for construction material were the bare minimum and thicker materials wouldnt show that much of a difference. Educated guess on that. But the minimum still should show exactly what you can expect. When it came to the gel, I wanted to keep everything the same across the board, and kept shots on the block to no more than 3 shots on each block. I even experimented with pork ribs to thicken the block and introduce bone material. I decided it was too difficult to replicate between shot to shot, so bare gel was my choice. Thanks for reading!

      The best length can be debated/tested for each caliber. However, you can open any length you want without a tax stamp if you but a pistol lower with a brace instead of a stock. For now, at least. The ATF is probably looking at braces real hard.
