This is why I don't think that RWBY 'projectile' weapons use bullets at all. The energy they release in propulsion mode is just too great; it's got to be some kind of Dust trickery. I'm pretty sure they'll turn out to be effectively directed energy weapons but using some kind of Dust reaction so they have 'shell casings' full of the Dust in question that's ejected after use.
