Why? a railgun utilizes an electromagntic firing system, yu want something metallic which will be pulled by the generated current, rounded for ideal aerodynamics.

You can also embed a dust core in such a projectile for elemental shots.

Not to mention railguns are EXTREMELY powerful compared to traditional weaponry. Real railguns are using pointed rounds that look more like contemporary bullets than ball bearings. You could use ball bearings, but pointed projectiles made for the job would be more effective.
