Black powder muzzle loaders are still firearms.

A spud gun is legally a firearm in Texas. TPC 46.01 defines firearm as:

'(3) "Firearm" means any device designed, made, or adapted to expel a projectile through a barrel by using the energy generated by an explosion or burning substance or any device readily convertible to that use...

So, since a spud gun uses an explosion to propel the projectile, then it is a firearm and you have to follow firearms laws for use. This means a city can control the discharge of the firearm within it's jurisdiction.
