"Cardboard Kevlar" - FACT or FICTION? Can plain old cardboard stop 15 calibers?
 
Did a youtube video to debunk a myth about "cardboard kevlar" - what some beleive to be as using several layers of thick cardboard to stop bullet penetration.

Yeah. I thought it was crazy too... but you should take a watch... kind of interesting what we came up with.

here's the overview:

In this video, we put 2ft of flattened desktop cardboard boxes to the ultimate test... to see if it can substitute for the mighty body armor that is Kevlar. Will cardboard holds its own? Or would you better off hiding behind a wall poster? Watch to find out! If your looking for shooting videos and pics of the shootout, skip to 20 minutes in the video. First 20 minutes is myself covering the topic at hand, outcome, ballistics, ammo, and weapons used.

Calibers tested:

.22 HP
9mm FMJ
.380 hp
.380 FMJ
5.7x28mm
7.62x25mm FMJ
.40 FMJ
.45acp FMJ
.45acp hydrashock
.500 s&w HP
5.56 nato / .223 FMJ
7.62x39mm FMJ
7.62x51mm / .308 winchester boattail FMJ
7.62x54r FMJ lightball

Weapons used:

Bersa .22
Bersa thunder .380
Walther 9mm
S&W M&P .40
FN Five-Seven
Springfield XDm .45acp
Yugo 7.62x25mm pistol - Tokarev model
Smith & Wesson .500 revolver
Bushmaster ACR enhanced
Robinson Arms XCR-L with 5.56 and 7.62 kits
Arma-lite AR-15
FN SCAR 17s (.308, or SCAR-H[eavy])
Yugo SKS
Mosin Nagant Rifle


Note: this was tested with corrugated cardboard (the usual type for packing and shipping stuff). There is non-corrugated, and some of the folks over at xcrforum.com have tested only a foot of it - stating alot more caliberzs actually failed to penetrate as well (awaiting video/photo confirmation of this though)


hopy you enjoy!

interesting stuff. Very long though. Should of made a cut, of shooting the cardboard with different calibers.... thats all we really needed... Could have been a 3 min video.

i hate to say this but thats not how kevlar works :( i thought you were gonna spin the cardboard into a fiber and make an actual cardboard cloth and shoot that!!

stack up enough feathers and it will stop a 16" naval shell....

This is useless info but a ginny can deflect a .22 bullet if you shoot the ginny while its facing you..dont ask me how i know this.. :-)
