PC §9.31. SELF-DEFENSE. (a) Except as provided in Subsection
(b), a person is justified in using force against another when and to the
degree the actor reasonably believes the force is immediately necessary
to protect the actor against the other's use or attempted use of
unlawful force. The actor's belief that the force was immediately
necessary as described by this subsection is presumed to be reasonable
if the actor:
(1) knew or had reason to believe that the person against whom
the force was used:
(A) unlawfully and with force entered, or was attempting to
enter unlawfully and with force, the actor's occupied habitation, vehicle,
or place of business or employment;

The guy banging on the door could be easily construed as "attempting to enter unlawfully and with force". This should meet the requirements for the presumption of reasonableness under the law.

I still wouldn't shoot through a door myself.
