Harry and Black in Shrieking Shack

I have a question from POA and was wondering if anyone else found this
ponderable.

In the Shrieking Shack before Lupin arrived, Harry, Ron, and Hermione
struggled and fought Black off and tackled him to the ground.  Harry
then stood above Black with his wand raised to "kill" Sirius.  Now how
was it possible for Harry to kill Black with his wand when Harry did
not even learn of the words that brought the killing spell about until
Moody's class in GOF?  Even then Moody said that the whole class was
too young to cause any real damage to anyone.  So, how was Harry going
to kill Black?  Wouldn't Black realize that, well maybe not since he
was overpowered by three thriteen-year-olds?  How could a skinny
little Harry Potter kill large, though still skinny, ans older Black?

Thought I'd throw that one out.  Not sure if ya'll had discussed it
before.
