Try the Hornady SST’s. Their the copper jacketed sabot’s that have a 2,000fps muzzle velocity.

I work for a company that armors cars. You generally buy the glass based on the threat you want to defeat; much like the way you would buy body armor. Was this glass for handgun protection?

There is glass available to stop a .308. The transparent armor (plastic?) on box of truth may have been weakened by the previous shots, but the nature of the penetration makes it appear it made no difference.

I have never tested the glass with a slug, that’s a good idea, I’ll try that next time we take half a day off to do “research.” Now that I’m thinking about it; not sure where shotgun slugs are “ranked” so to speak.

The 12 gauge slug is amazing. The vest did stop the slug from punching through the kevlar, but there is no doubt that there would be fatal trauma regardless. I have heard it is a great tool for removing door hinges as well. Deer don’t go very far when hit with them either.

I haven’t heard anything about glass that lets rounds out but not in. Some of the ballistic glass used in the MRAP vehicles and HMMWV’s in the sandbox use a plyed type glass, but all I can think of for allowing outgoing rounds is the rifle ports on a RG-31 – http://en.wikipedia.org/wiki/RG-31 – they are made of armor plate and open up so a Warfighter can shoot out.

I am surprised that handguns did not have much effect until after several rounds. But then, these were “bullet-proof” glass, correct?

I am also wondering about a product I saw being tested a while back. A “sandwich” of glass/plastic layers, it was as effective at stopping incoming fire as other armor glass – but allowed outgoing shots in some way. Anyone know whether that has been successful?

Here’s the Box O’ Truth page:

They’d apparently shot it several times before using the slug. Hopefully it wasn’t weakened somehow.

My dad saw a film that was part of a government study in which several firearms were tested against stock passenger cars. The slug was the winner; it was able to go through doors, and in the case of one small car, was able to penetrate through the back of the car, the back seat, and through the front seat to where the driver would have been sitting. This was all done quite a few years ago. They found that all handgun bullets were deflected from windshields, unless the windshield was already weakened by several shots.

There was a website I saw a few years back called the box of truth or something like that where a man did a bunch of testing on locks, windows and other things. The 12ga slug was absolutely unstoppable. I’m surprised if bulletproof glass can stop .308 either.

HI!
Others also penetrated it but it took more than one round.

12 gauge slug at close range.

Guess what could penetrate those?

Umm…typical rifle rounds? A 12 gauge? A baton?

I dunno, I’m having trouble coming up with a believable guess here.
