From what we have seen from Ruby's and Yang's weapons, they don't really fire "bullets" in the same way we think of them in our world. Yang in the series shoots short range shots of what looks like fire or some unknown form of energy. She can fire the over a short stance, but they most likely just dissolve into the air over time. Ruby's "bullets" may operate on the same principle; except Ruby has been shown to have different types of bullets depending on what she loads (if the Trailers are considered canon). So Ruby may have one set for long-range if she is sniping, mid-range if she is in close quarters, and short-range combat for melee attacks. The short-range shells seem to serve the purpose of propelling her forward to increase her speed and as a result, the damage caused by her scythe's blade. So Ruby had a plan to defeat the Nevermore, meaning she may have had a set of short-range/speed-enhancing bullets at the ready and when she fired to increase her speed, the "bullets" didn't actually go anywhere because they dissipated instantly after firing.
