Okay so Junior's weapon isn't directly working with Dust or Aura. But for Blake's and Ruby's weapons, they could be using Aura based on what Pyrrha said about all their tools and equipment being conduits for Aura.

As for the dark clouds, if you watch the Red Trailer closely, the normal rounds that Ruby fires out of her sniper scythe give off white muzzle flashes. These fire off a bullet. When she loads that "special" magazine in her weapon, she is able to get some extreme recoil off of the blasts. Also the muzzle flashes are no longer white, they are black.
