-second, I have made awesome armor from cardboard, when backed with styrofoam it will stop just about anything...

If you are doing tests with materails with a thinkness i would say that you should try a more stable object that would have more mass.
That way you kno that every projectile will hit at the same speed(aprox), have the same mass, Will hit with the same amount of surface area(aprox), and will have the same strengh.

For a test projectile use a solid lead ball, a sphere is more stable out of a smooth-bore than an elongated projectile.

Make adobe brick out of the clay, three inches of that stuff will stop a thirty-ought-six.
Hey, what if you sandwiched three inches of adobe between sheet metal and one inch ply-wood, Sheet metal on the inside? The ply-wood would slow down the projectile the adobe would stop it and the sheet metal would prevent the adobe from fragging.

By the way incase nobody noticed, I like lead…a lot…

you could just use lexguard, at 3" thick it will stop a direct hit from a morter. Should work for your purposes.
