The brand name I am familiar with is the Glaser Safety slug ammo. They compress lead birdshot into a bullet jacket to form the bullet, it's supposed to come apart on hitting almost anything. There is a "silver" and a "blue", depending on what size of birdshot is used to form the bullet. This ammo is pretty expensive, and the bullets are not available for reloading.
Some of the new non-toxic target ammo is supposed to have bullets that are formed from metal powder and disintigrates when it hits a solid backstop. I don't know much about this kind of ammo.
