Typical centerfire FMJ ammunition is not lead free. It is a lead bullet with a thin copper jacket on it. For most FMJ the jacket doesn't even enclose the base of the bullet, so in a high-pressure round there is still some lead that gets vaporized with every shot.

Lead-free ammo is made of ... "other stuff," such as some recent offerings that use solid copper bullets.
