The Box O’ Truth #14 – Rifles, Shotguns, and Walls

In our last tests shooting walls, we tried to line up 4 walls that were 2 feet by 2 feet.

It turned out that the 5.56 deviated so much from its course after the first wall, that it was almost impossible to hit the other walls to test penetration.

So, we built bigger walls. These are 4 feet by 4 feet. They are normal 1/2 inch drywall or sheetrock, as it is called in some areas. We spaced the walls about 10 feet apart to simulate normal across-the-room distances.

We will be trying to see how many walls will be penetrated by the rounds shot today.

14-1

We tested common pistol rounds last time and they all went through all 4 walls without any problem.

Today we will test some rifles and shotguns with various rounds.

First an AR15 shooting XM-193 Ball.

14-2

It went through all 4 walls.

That’s right. All 4 walls.

It was tumbling and deviated from a straight line of sight, but it went through all 4 walls.

This is the entrance of the 3rd wall.

This is the exit of the 4th wall.

This is the exit of the 4th wall.

Then we shot Remington 55 gr, Jacketed Soft Point ammo.

14-5

It went through all 4 walls also.

It was clearly mushrooming, but then broke into two pieces.

14-6

This is the back of the 4th wall, where you can see the two pieces and one penetrated and one was stopped in the wall.

Then a round of Frangible 5.56 that my friend Hardshell sent me.

It is not designed to work as an anti-bad-guy round, but let’s see what it does in drywall.

That's the entrance into the second wall. It had broken into 4 pieces, but they were still penetrating.

This is the entrance of the frangible round into the 4th wall. Notice the spread.

Due to many requests, we tried a round of Winchester JHP from the .30 Carbine.

Caught the round of brass in the air just behind the front sight.

14-10

Continued below...

It penetrated all 4 walls.

This is the entrance into the last wall. Looks like it was going sideways.

Time for the shotgun.

First a round of Remington Reduced Recoil 00 Buck that my friend ARKAN_the_Tiger sent me.

I have been curious about these rounds.

The Laws of Physics are unforgiving. You don’t get something for nothing.

Reduced recoil should mean reduced terminal ballistics.

Sure enough, the recoil was obviously less than normal.

14-12

It penetrated all 4 walls.

This is the entrance to the first wall. Notice the dents made by the plastic filler balls.

This is the last wall. Quite a spread of 00 Buck.

This is the last wall. Quite a spread of 00 Buck.

Then a round of Hardened 00 Buckshot that my friend Blain sent me.

After the reduced recoil round, this one kicked like a Missouri mule.

14-15

It also penetrated all 4 walls.

This is the last wall.

This is the last wall.

We get a lot of questions about the effectiveness of Birdshot.

I shot a round of Remington #8 Dove Load.

14-17

It blew a big hole in the first wall.

14-18

But the shot did not even break into the second wall.

The only hole was from the shot cup.

14-19

This is the back of the second wall. No damage.

This is the back of the second wall. No damage.

Lessons learned:
  1. Contrary to what we have been told, XM-193 does not seem to “fragment” when shot into drywall walls. After we were through for the day, we even shot several more rounds of XM-193 into the walls to see if we could get one to fragment. They did not.
    It is clear that they were tumbling and deviating from the flight path, but they were still penetrating the walls.
    Now, before anyone says it, No, I do not know how much damage they would do to someone after the 4th wall. But they would do some damage as they were still penetrating.
  2. Remington 55 grain JSP and Frangible 5.56 also penetrated all 4 walls. So did the .30 Carbine.
    When shooting rifles, walls are concealment, not cover.
  3. 00 Buck penetrates 4 walls with ease. It is a great “Stopping” round, but there is a price to pay.
    Until someone invents a “Phaser” like on Star Trek, anything that will stop a bad guy, will also penetrate several walls.
  4. Birdshot does not excessively penetrate drywall walls. But it does not penetrate deeply enough to reach a bad guy’s vital organs. Birdshot makes a nasty but shallow wound. It is not a good Stopper.
    Use Birdshot for little birds. Use 00 Buckshot for bad guys.
  5. The sun was shining, it was a lovely day, and it was fun shooting stuff.

Thanks to my friends for the ammo to test. Thanks to Tman and our friend Richard who was visiting from out of town, for the pics.

  1. This test is not valid for depth of penetration into flesh, actual meat is:https://youtu.be/gq3RVvL9ZjU

    That video proves birdshot, inside the home, is devastating to meat and bone. Through a rib cage, through a pork shoulder and destroys a shoulder bone.

  2. My question would be, if I had to shoot more than 12 rounds out of my 12 gauge, could I switch to my SKS? Saw a conversation on warriortalk where the instructor concluded by saying .30 caliber will go through a barrier and keep going, more than .223. I would like to have something magazine fed for worse case home invasion but would prefer not to use a round that will penetrate more than most in an urban environment (ie my neighbors arerightnextdoor). At the same time, the 12 gauge recoils so much that there is a limit to how many times I can shoot I would think. Finally, I don’t want to spend a ransom for another long gun. I was thinking Kel Tec Sub 2000 maybe but would have to see that the nannies here wouldn’t wet their panties- ie I’d have to restrict the amount of evil black rifle features on it. Furthermore, not sure that a PCC would perform well enough against rifles and bodyarmor. Maybe a used mini14 in .223 is the way to go? Not sure.
