The same thing 9mm bullets are made of, and 7.62x39 bullets, and... well, bullets in general. The case can either be brass or steel. The projectile will primarily be lead. It may have some other type of metal inserted into it, and may or may not be jacketed with copper.
Bullets can be made from many materials including wood, steel brass, copper, lead, tungsten, bronze, plastic, etc.

Mild steel is one of the less expensive replacement options for lead in bullets.
