I know this is not interesting, but how thick was [metal] has to be to be bulletproof?

I want to know how thick it can have to repel 50 cal. It is a project I'm working and this is desirable.

The standard military armor piercing .50 caliber round penetrates 1 / 2 "of steel plate at 100 meters at an angle of 90 degrees to the surface. In order to determine their response will have to determine what everything is skyrocketing, how far, and at what angle. Lead is considerably softer and denser than steel. You need a reference to compare steel and lead, as ballistics. Good luck.
