They work fine.
Powder burns happily in vacuum. There's no air in the cartridge anyway. The hard part is keeping things lubricated properly, and radiating heat from the weapon. Brass cartridges are great at removing heat from machineguns, while big metal barrels with caseless ammunition tend to get dangerously hot.
That, and guns work without batteries. That's always a bonus. No good having a multi-megajoule railgun if your generator's been shot out, or if your enemy is too flimsy to dump all that energy into their structure without punching through-n-through.
