Scene in which Expulso appears, DH, Chapter 9:
The force of the Death Eaters’ spells shattered the tiled wall where Ron’s head had just been, as Harry, still invisible, yelled, “Stupefy!”
The great blond Death Eater was hit in the face by a jet of red light: He slumped sideways, unconscious. His companion, unable to see who had cast the spell, fired another at Ron … “Expulso!” bellowed the Death Eater, and the table behind which Harry was standing blew up: The force of the explosion slammed him into the wall and he felt his wand leave his hand as the Cloak slipped off him.
The “great blond Death Eater” is Rowle, who is knocked out. Therefore, the other Death Eater, later identified as Antonin Dolohov, is the one who uses Expulso.

I get why this comes under Charm, but should it really also be under Transfiguration? Transfiguration is considered "the art of changing the form and appearance of an object". Now admittedly, when Dolohov used it in the caféon Tottenham Court Road, and it hit a table causing it to explode, the form of said table was changed. But, I'm fairly sure Transfiguration is more about changing on a molecular level, rather than just smashing something up. Otherwise, such spells as Diffindo (Severing Charm) Bombarda (provokes small explosions), and Confrigo (Blasting Curse/Charm), as well as curses like Crucio which can cause an inanimate object to shatter they miss the target, would also be Transfigurations, when they're clearly not. So, anyone with me on this?Nia River 00:22, November 27, 2010 (UTC)
