How many steel plates does it take to stop a 308 or a 300wm? With pics.
Remember, I do this to entertain me, not you.

Depends on heat treat, steel type, plate thickness, and round type.
Seeing .50 BMG punch big holes through lots of 3/8″ plate stacked together is pretty slick.

Company I know has an armor product that will take mutiple close(~2″ apart) hits of .50AP and APIT at point-blank(~25′) range. Material weighs about 26 pounds per square foot.
Also saw the same company shoot 100 rounds of 7.62X39 steel-ball into a six-inch circle of one of their products without any rear-panel penetration. That was impressive.

It also depends on the ammo construction. See also my tests on AP ammo.

It sure doesn’t look like a 3/4″ plate. It looks like three 1/4″ plates. Big difference. Penetration happens when the steel shears in front of the bullet due to the high pressure. This shear is disrupted and the pressure is dispersed somewhat more when you have multiple plates. That’s my story and I’m sticking to it.
