Every so often someone brings out a new design of bullet for the defense market. Fragmenting bullets are one of the basic designs. Generic advice is to stay away from them.

The Black Talon was not a "novelty" bullet. It was the marketing that made it seem exotic and caused the uproar among the antis and soccer moms. It didn't go away, just the black color. It was introduced in the late 80's or into the 90's best I recall. Good ammo.
