With a maximum possible 6600 rpm fire rate, 20mm Vulcan rounds, and the possibilities of anti-armor (or some kind of high impact) rounds and extra potent Dust for propellant mixes, I can buy Coco sawing through targets such as a Deathstalker.

Another possibility: Maybe she was out of her best ammo because of all the Dust robberies.
