Letter Re: Ballistic Protection of Building Materials

Tuesday, Oct 11, 2005

Mr Rawles,
I saw the letter you posted asking about the ballistic protection afforded by common building materials. I did some experimenting on this topic, testing the protection of concrete-filled blocks against a number of common calibers. You can see my findings here:

Even 8 inches of concrete offers only temporary protection from rifle ammunition (though it's quite good against pistol fire.) For info on other materials, you might direct folks to: http://www.theboxotruth.com/ - Ian
