If the bullet starts tumbling from the first round, if there's enough time it will go sideways, increasing the surface area and decreasing penetration. so the distance would probably make a difference

Lowest velocities due to shorter barrel + more stability due to fast twist (55/62 gn./7") = least damage.

Rifle rounds of the correct caliber and construction are safer than ANY pistol round and most 12 ga rounds. This is among the main reasons L.E. migrated away from sub guns and shotguns. It's counter intuitive. Hi-vel rifle rounds with thin jacketed, non bonded soft point construction (.243 and smaller) are actually way safer than pistol rounds for home defense . ln .224, 62-64 gr non-bonded soft points and the sierra match kings (77 gr fer sure) frag VERY quickly...like 1interior wall. after 2 walls, they are pretty much neutralized. The 'barrier blind' rounds are a crap choice for home defense for this reason. Frangible rifle ammo is made to disintegrate on steel, not drywall. Pistol rounds and 00 buck will go through at least 6 interior walls, likely 8+

[@shibaspeed]

Brick will stop it. Check out Tactical Rifleman's video

[@thelz7909]

Most likely, they are brick veneer and the brick only provides a very minor level of protection. Flowerbeds filled with sand that is several inches thick will provide much better protection.

[@Carterwray1]

The only thing I would really say as a factor would be the fact that once those rounds start tumbling and they tumble all the way through the full length of a room they are going to slow down substantially while tumbling as opposed to just flying straight. Apart from that still pretty well demonstrates how important it is to know where your rounds are going. First couple of walls are the important ones.

[@knndyskful]

“We have no way to measure the speed of the bullet” Um, Tim...wouldn’t a chronograph work?? Just put it at the other end of the test medium? Or put one in front and one behind or something? Ah and now that I’ve seen the rest of the video: the chronograph can’t track tumbling bullets

[@bobdinovo6889]

I am very very surprised. Thank you for opening my eyes 👀. I can't wait for the PCC video

[@billjacon4527]

When these tests are done, how come insulation isn't used? That comes into play to a extent no?

[@alexmartin9177]

an entire bundle of fiberglass insulation will have almost no effect on a bullet. Most homes only have insulation on the outside wall. 3.5-5.5 inches (2x4 or 2x6 ext wall) of fiberglass insulation has no effect on a bullet.

[@mattwalters6834]

From what I’ve heard, no.

[@Dillpickles719]

This is why knowing your target and what’s behind it is so important. You don’t want to shoot anyone by accident.

[@dorrintheengineer]

Love the videos, Tim, always. This one nearly killed my husband and I. For the love of all that is holy, it’s “frangible,” not “frangidable.”

[@Vadim3814]

Why don't you build a house from a bricks?

[@jt2475]

[@huntertice3883]

most newer houses are made on a wood frame because it is cheaper to make them at such a large quantity.

[@fancyultrafresh3264]

"Through the windoooooooooows, through the walls! All that 56 ball!"

[@almostghosts]

This test is accurate if you live in a house with walls two inches apart.

[@misobeno]

This 100%. Even interior drywall generally has a few inches of space between each layer of drywall. For a worst-case scenario, shooting from a room through a hallway into a room will add a few feet of airspace between each wall.

[@almostghosts]

Miso Beno Totally and the round is probably losing a lot of velocity as it hits each wall then travels through the airspace between rooms. I would like to see a similar test with the drywall spaced apart far enough to represent rooms in a house.

[@valhallindustries9317]

Thanks for making this video. Really debunks this urban legend that has come to permeate the arms industry that standard 5.56 rounds "are the best option for home defense because they penetrate least". Least being a generously relative term. I am also fully aware of the argument that buckshot out of a shotgun is quite obviously the least penetrating projectile load possible, and I am making this point specifically regarding projectiles fired from a rifled bore, handguns included.

[@trollmcclure1884]

buckshot is nasty. you meant birdshot right?

[@erebostd]

This aren’t „walls“ this is cardboard. Who would use something like that for walls? Come on!

[@bavarianshooter]

US homes... kinda scary. If i fire my AR in the room I'm in right now, it propably wont't go through my inner wall. I have 42,5 cm bricks on the outer wall and 35 cm bricks on the inside.

[@JamesSmullins]

Most newer homes are built with these types of materials. They aren't built to last like they used to be. It's build them fast and cheap so that you can maximize profits. Unless your home is built using block or bricks it's built pretty cheap these days. This is why it's best to have your home built to your specs rather than buying homes from developers.

[@xORLOCKx]

Yeah... this is what modern homes are made of in the US. Pretty sad. But I live in a full brick house.

[@CharlieMikeNS]

[@TheJukkis]

I think insulation is pretty important part of walls and they provide some hinderance to the projectile, and its missing from this test. Also a bullet fired from 20 inch barrel would be cool too.

[@nmtay]

Makes me glad that I live in a house with a brick exterior. I know it's not impervious and there are still windows that offer little protection, but that brick will certainly offer a lot more protection that some of the more modern building materials.

[@bretthompson3865]

Hate to come down on your test, sir, but up here in Washington state I built houses and commercial buildings for decades after I got out of the Army. We don't use chip board for wall sheeting. Up here you're looking at 3/4" or so of wood siding over a layer of 1/2 or 5/8" exterior plywood behind which is 5 1/2" of fiberglass insulation. It's 2x6 exterior walls up north. Only then do you get to the drywall. Believe me, the results will vary considerably.

[@YoderTexas]

Those sheets of chipboard will stop more if they are touching each other. The presents of the second sheet, against the first, prevents the blowout of material. That means that there is no place for the splinters to get out of the way, making it harder to penetrate. Clamp them together tightly, as if a solid block of wood. Yes, you can use duct tape.

[@TheOnlyNasa15]

Nice video. Was great to see the penetration and the tumble progression. My only issue with the test is there should have been more space between the pairs, but I get that's not feasible without you building a house to replicate. either way great vid

[@lukew2194]

kzbin.info/www/bejne/hpPHnoRrfrNloJI

[@DroneWolfMedia]

Would be interesting to see a similar test using concrete block behind the siding or stucco. Most homes in Florida are built with concrete block due to hurricane building codes.

[@MustPassTruck]

This test also doesn't have the hard plaster coating on the drywall. Some older houses have 1/4 to 1/2 inch of hard coating. That stuff is like hitting a brick.

[@albertsalcedo8675]

That moment at 6:09 when Crockett and Tubbs are heading out for a drug bust. Pure 80's vibe!! Lol!

[@duceanahalf]

Id like to see this on a traditional Florida home. stucco, CMU block, and interior walls are finished in a plaster that is hard and brittle.

[@duck-n-cover477]

A simple .22 charge is used frequently in a tool designed to drive hardened nails through dimensional lumber and into masonry and concrete!

[@theiviachine]

I like how you are teasing me running that SIG MCX that has been sold out for the past four months everywhere 😪

[@molotov_mountaineer]

That's cool you own a Colt 6940P, I've heard a lot of good reviews about that model and it's becoming a very desirable collectable.

[@StPaul76]

That frangible round effect reminds me of sand blasting which is a craft I quite often do for living. Enough velocity and amount of particles does havoc on pretty much everything except metals and granite stone. My boss once put the sandblaster fosset out of his hand to move around some stone wall building air valves which he was blasting.. The pressure/sand hose is thick and stiff and it rolled.. Turning the trigger lever of the fosset against the steel table he used as a stand.. He got a blast of quarts in his thigh with such a force it went through thick denim working pants, one layer of jogging pants and two layers of underwear (Finland during winter time working outside)and about 2" into his thigh muscle.. Tiny bits of sand kept coming out his thigh for 5 years.. He was lucky not getting the blast into his nuts thats for sure..

[@stefanmolnapor910]

I was hoping for a simplisafe reenactment and or simplisafe destruction test! Either way great video... as always!

[@josholdham1033]

looking healthy! Hope you and the family are well

[@Jazzman-bj9fq]

Great test! I've had a few discussions with folks and disagreed with their assessment that a 5.56 rifle is superior for home defense over a pistol or PPC because their claim was that since the 5.56 is going so fast that it is more prone to fragment (M193 type round, solid fmj) whereas the PCC or pistol rounds would pretty much always penetrate. Apparently over 3000 fps of energy even in a small fmj round says it all.

[@johndoe-td2xd]

FMJ is great for penetrating barriers, horrible for home defense. Rifle rounds of the correct caliber and construction are safer than ANY pistol round and most 12 ga rounds. This is among the main reasons L.E. migrated away from sub guns and shotguns. It's counter intuitive. Hi-vel rifle rounds with thin jacketed, non bonded soft point construction (.243 and smaller) are actually way safer than pistol rounds for home defense . ln .224, 62-64 gr non-bonded soft points (winchester-power points for sure) and the sierra match kings (77 gr fer sure) frag VERY quickly...like 1interior wall. after 2 walls, they are pretty much neutralized. The 'barrier blind' rounds are a crap choice for home defense for this reason. Frangible rifle ammo is made to disintegrate on steel, not drywall. Pistol rounds and 00 buck will go through at least 6 interior walls, likely 8+

[@Megames2012]

I run the 55gr Critical Defense in a 12.5 inch pistol with the SBA3. Solid option. 👍

[@hyperfocal2002]

One test with frangible that might be interesting and more realistic would be an outside wall, then an inside wall 10 feet away. With closely spaced material, the frangible round pretty much is bird shot, so its energy is going to be retained. Even with ball, it would be interesting to see what happens when a round goes through an outer wall, passes through a simulated room area, then hits another wall.

[@poolhub8-9]

I believe the "dust" you kept referring to was the drywall powder from the previous sheet. Nice vid.

[@mattwalters6834]

Nice SCAR

[@chzzyg2698]

This is why I chose .45acp for an apartment in a busy city. It'll probably blast through walls too, but I know dirt cheap .45acp ball is much slower out the gate than 5.56. I even considered .380, but I don't trust .380 against a flash mob breaking in. It'd be interesting to see some .45acp test's.

[@derrick9653]

I believe that you would see a different result in a house for the frangible round. After the frangible round hits and pulverizes it SHOULD essentially turn into powder and over the space of a room spread and dissipate. If you have your outer wall simulation spaced well away from the next wall it will likely not penetrate nearly as far.

[@mohawk3371]

For testing frangible ammunition the spacing between the walls is important, as the bullet particle need time and space to separate. The separated the bullet fragments individually have less energy, which will effect penetration. A proper test should have 8-10ft between every pair of sheet rock slabs.

[@bbhrdzaz]

If you could put a chronograph after the target, you could determine the energy remaining in the bullet. from the looks of the exit, it does appear that the bullets are intact.

[@bray1952mj]

Sorry, I'm late to this video, I just hit the bell for update times. My guess for a safe spot in your home if you hear gunfire. 1. basement if you have one, 2. on the floor of a tiled shower. I have watched Paul Harrell use tile in a backpack with a thick book and it stopped a bullet. This is just my guess, that a tiled shower wall should stop or greatly reduce the velocity of a bullet. If that tile was attached to a cement board backer even better. This would be a good test, for penetration from a pistol,l or rifle rounds. Tile attached to gypsum board, and tile attached to cement board, vary the tile sizes, dimensionally LxWxH plus thickness. Does a tiled shower offer your family protection while you investigate gunfire that may have already come through your home?

[@MichiganManiak]

Well, my neighbor shot my pole barn with a 10.5" barrel. He was approximately 260yd away. The bullet skipped off the ground at least once because I saw it happen. It went through the metal siding, 3" foam board, 6" of fiberglass and one sheet of drywall and hit my tool box. Didn't even dent the tool box.

[@cameronnorton5898]

I wish MAC was still viewer supported.

[@Militaryarmschannel]

We are. Simplisafe sponsored this one video. Sadly, viewer support is way down so we have to find such sponsors that don’t conflict with our ability to be brutally honest about guns we showcase. If more viewers chipped in just $1 a month we wouldn’t be forced into doing integrations like this. 👍

[@hal6165]

This may be old school, and by OLD, I mean black powder era old. Take a metal plate, attach to a pendulum and measure the angle that the plate moves when a bullet strikes it of a given mass versus the known mass of the plate mechanism. The force of impact pushing the plate should help you determine the velocity of the round when it strikes it. That was the methodology used to measure velocity of cannon balls back in the early 1800's for black powder smooth bore cannons. Don't know if this would help or not.

[@Militaryarmschannel]

There are factors to be considered using this method too. If you hit high, middle or low on the plate you will get different results, as an example.

[@Mike-gf7fi]

I was working on a bad trigger, then testing cycling function I accidentally shot a 55 grain round the house. It went through a small lock box with concrete liner, then the wall, then through my tv, then through a wooden table leg 5” thick and got stuck in a wall. It went through so much more than tv and movies portray

[@williamclaxton2194]

Tim, I'm very interested in this subject for home defense. Been doing some research. What about these?: Remington 62gr .223 Ultimate Defense Hornady Critical Defense RIfle 55 Grain FTX 223 Speer Gold Dot Personal Protection 55 Grain in 223 Hornady Varmint Express Ammunition 223 Remington 55 Grain V-MAX

[@davegrenier1160]

Having gelatin behind the target for the frangible rounds would have caught whatever was transiting the materials. It would have been interesting to see if what was coming through had any solid parts left or if it was just a stream of high-velocity powder. (We know the ball was passing through essentially intact. No need to use gelatin in the testing of ball.) If only powder was coming out, then barriers could have been removed one at a time to see how many barriers it takes to reduce the round completely to dust.

[@blahorgaslisk7763]

Some time back another channel tested this and their results was very different. Sadly I can't remember the details, or even what channel it was for that matter, but I do remember that after the testing they came to the conclusion that 5.56 was very bad at penetrating drywall. In their testing the bullet broke up at the first wall and was more or less harmless after that. They tested against 9mm from a carbine which penetrated more walls than the 5.56. As a result their conclusion was that 5.56 was a good choice for home defense in an urban environment. The results in this video is much more in line with what I'd expected, apart from the frangible rounds that is. Now I do not think the other channel was trying to pull a fast one, but I really don't can explain how their test results could differ that much. One thought that just hit me is that it's possible in that other test (on that channel I can't remember) they used subsonic ammunition to keep with the home defense idea. No matter what details my beginning signs of dementia has wiped from my memory it was interesting to see two so different results on this.

[@Fugettaboutit]

I think it would have also been good to place some ballistic gel or a flesh-like medium behind the layers/harness to maybe show how damaging the bullet still was after penetration....although I guess you can still get a sense of at least its velocity and structural integrity from the holes. Good stuff.

[@JosefCharoni]

If you actually spread the walls with realistic wall spacing in a house the frangible will penetrate way less with the distance for the projectile/powder to disperse In the air and not stay concentrated with no spacing

[@AlphaRomeoOneFive]
