I am very new here and this is my first thread started.

I work for a very small company that manufactures small buildings. We occasionally have a need to supply bullet resistant structures for various clients.

The standard we must adhere to is stopping a 180 grain JSP .30-06 projectile at a range of 15 feet.

Currently, we use 1/2" plate steel behind our normal facade. With the weight and cost of steel these days we are looking for other means of stopping the bullets..

Ideas? I have tried a kevlar fabric, but the cost is as much as steel for the amount needed to stop it.
 
Would a combination of the kevlar and ceramic plates in modern vests be apropriate and a whole lot lighter?
 
You can also do good work with fiberglass panels. In a fixed structure there isn't the weight or size premiums that would force you to use Kevlar or more expensive materials.

If significant exterior facades like brick or steel are involved it takes a lot less to slow a bullet that's already been deformed, fragmented or slowed down somewhat.
 
I read somewhere (the box o truth maybe) that sand works really well fill a hollow wall with it or fill cement blocks with it, or fill bags with it.
 
The shoot-house I built consisted of steel plate and big blocks of rubber made from ground-up car tires. The rubber alone stopped 7.62 bullets cold.

The parts were manufactured by Range Systems, inc.
 
Kevlar is going to cost more than steel by a long shot. Sand is great, but the weight adds up fast and it's not going to work for a large building. Water would be good, but again the weight can become enormous. Building underground or inside an earthen mound is about the cheapest I can think of, but pretty weird. The ground up tires are a good idea.

What about compressed straw? Not the bales, but the stuff they're using for building materials. If it's anything like the wet mounds of straw I've shot at it should be a very good bullet stop, while bearing its own weight.
 
Thanks for the replies, some good stuff here for sure.

Tell me more about the stuff made from tires.. Interesting to say the least.

Concrete is a very good stopper, but very heavy and would take a lot to get into place.

Looks like next week will be one full of research.

Thanks again!
 
Here's a picture of some of the construction:

WINGNUTX has it
at work we got some rubber belting 3/4" from a big mill.It was used as a tread to roll the logs while debarking. We use it to pad while lifting heavy objects. I brought some home that was all torn up. I dont own a gun that'll shoot through it
 
Very nice, but I think a bit bulky and spendy for the application. We are trying to replace 1/2" x4'x10' plate steel with something ideally lighter, less expensive and easier to work with.

The fiberglass panels might be the best direction, will check on cost ASAP.
 
well

Maybe this will help?

you already said you dont like concrete, though and that is in the first combo that will stop a 270 winchester. Not sure if Ballistic fiberglass is what you want, either.

But this site does give a cost breakdown.

Have you considered shot-crete in the sides of your structures? I remember once upon a time reading about the monolithic dome structures being able to stop a 30-06. They use shot-crete in their construction.
 
Dirt. Reusable and cheap as all getout. Not good if there's termites. I think tires were the original source of kevlar - so the things are pretty tough. Ground-up tires may be the way to go.
 
Both great ideas. I had thought of simply filling the wall cavity with sand, but was curious as to what would keep the sand from simply draining out after a shot.

I have no experience with shot crete, but will do a search for it.

Our typical building is relatively lightweight and easily picked up with a forklift or crane and transported by truck.

Here is hopefully a pic of a typical structure I want to protect.

What keeps it from emptying... it's a solid, and sticks to itself. Get a cereal box and fill it with sand. Stab a hole in it with a knife. Most of it ought to stay inside. Could be different for extremely fine sand, but the fact is that sand is a solid, not a liquid.
Also, sand might work well as insulation if you end up sticking it in walls.
 
Well, I don't know what *will* work, but an 18" thick layer of cream cheese definitely *will not* stop a 30-06JSP from 15 feet. It looks really freakin' cool, though; 15-20 yards of splatter, and a bunch of wildlife eating well for a couple of days.

Doesn't do too well against 45ACP JHP or 22WMR JSP, either. It did, however, slow down a 380ACP HydraShok enough that it was just laying on the ground a few feet behind the cheese.

So much for my plans for affordable cream cheese based body armor. Too bad I don't still work for a place that sells bulk cheese to employees for a few cents a pound when it gets too close to the sell by date to account for shipping times. Pepper Jack was on my list for testing next, but I'm not paying grocery store prices for it.

Tall order if it can't be bulky either...
