User blog comment:ChishioKunrin/My view on Dust (so far)/@comment-24620600-20140307092353/@comment-3146930-20140307201810

From what we have seen, Dust-bullets come in a lot of shapes and sizes. Ren and Ruby both use traditional bullets while Nora uses a freaking grenade launcher. However we have also seen Yang use shells in her gauntlets, but they fire in the form of a semi-shapeless mass, appearing more like fireballs. However we haven't seen Yang carry around and Dust crystals on her and the power seems to come right from the shells. Her weapon is also very similar to the shots Roman fires from his cane. All I'm saying is that it is less likely that Roman carries around a bunch of Dust-crystals and more likely has a set of shells loaded into his cane.
