I didn’t know that Chinese owner’s manual translators were firearms enthusiasts!
Lots of variables to consider.
Moisture content
Thickness
Grade of filler.. fireproof drywall, waterproof, ....
Spacing between sheets
Age.. as drywall gets hard and brittle as it ages
........
They should use better insulation...............
I think I have heard that more people are killed by .22’s than any other caliber. But that could be dated.
So many with 9mm and .45ACP for concealed carry. Have 2-shot .22 Magnum derringer which you will never know is pointed at you until fired. Pity the poor fool....
Thank you for this!!
How much old plaster?/jk I have a house with some bullet holes in it. I know a medium grade linoleum with masonite underneath will absorb .38, but I’m not sure what went into (and through) the old walls. Sure made a big mess.
That’s a very convincing demonstration of why body-armor plates are not made of gypsum.
Interesting. I have some fresh drywall and will test it next time we go out. I am very surprised that a 22LR can go through so many layers. Sounds like an excellent project for my twin 8 year olds and their Ruger 10/22 assault rifles.
The real question is...
How much cranial-bone is required to stop a 0.22LR fired from a handgun?
We are in perilous times.
not sure but a gas powered bb gun can go through 1/8 pine and damage what was inside the crate- I got the spanking to prove it
A 4” wall faced with sheetrock is not bullet proof. But, fill it with crusher-run stone and it will stop 50BMG.
Even drystacking concrete cap block in the wall cavity will stop all handgun rounds, and most rifle rounds.
Fema has free building plans on the web on how to harden walls to withstand “flying debris”. Cheap and effective, stops bullets, too.
for INDOOR home defense get a Circuit Judge
It fires both 410 shotgun AND .45 cal bullet.
So you have the best of al worlds
410 indoors will kill you dead without taking out a structial support or going through too many layers
Well nuts! I had been planning on making selling bulletproof vests constructed out of drywall; guess I need to reassess and go with drywalls.
Also, is this Chinese or American drywall?
I was thinking 3-4 but I also envisioned them being against each other vs. spaced apart. I’m willing to bet that would be the case.
Before I watched the video, I was thinking about the factors that would affect the bullets.
First off, I thought there might be a small amount of flex in the sheetrock because it was only secured loosely at the bottom between 2x4 blocks. Installed sheetrock would be more firm as it is secured all around and held in place with multiple nails/screws fastened to studs.
I also thought there might be some leeway in the barrel pressure in the lever-action rifle vs a semi-auto rifle like a 10/22.
Then, there’s the silencer on the pistol. Most home defense pistols aren’t gonna have a silencer, so that’s not a real-world scenario.
But then...
I watched the video, and all of the above just didn’t seem to matter. With most rounds going thru 8-9 layers...
Just wow.
.22LR? I have some dim misty memory from the past of actually being able to BUY them so I could fire my now-useless, empty .22 rifle.
From a long rifle barrel, not surprised.
From a short pistol barrel, it will be less.
