You know what? This is what I'm doing with the weapon. The shotguns are semi-automatic, carry 6 rounds each before needing to be reloaded, and each normal round is released in a spread pellet format with high stopping power and slight incendiary properties due to being fueled by Fire Dust. However, as a secondary firing mode, the weapons can charge and shoot a single concentrated fireball-like blast.

What would the ammunition for this be like, bearing in mind both what shotgun shells are normally like and how the Dust functions?
