The specifications for the required ammunition are well-known. The stuff is harder to make than the firearm, however. For that to differ you'll have to use something substantially higher- or lower-tech, e.g. caseless or black powder. And caseless ammo is only easier to produce if you disregard the difficulty of producing a practical propellant.
