[X-Men] Could Magneto potentially use his powers to act as rail gun?

I need to know. How would this work? Would he increase magnetic fields around him or something? It'd be pretty badass.

Does Magneto have the required level of power? Yes, recall how many times Magneto has stopped multiple bullets from regular firearm, which just replace magnetic acceleration with chemical reaction.

Does Magneto have the required accuracy? Yes, recall how many times a Magneto control a tiny speck of metal to accurately take down multiple threat. Even without one he can just attach a barrel to his hand and making pew pew sound.

A better question though, why would he? A railgun bullet can't turn around a cover nor taking down a flying target without killing them. A continuously controlled metallic contraption serve his need better than a small metal moving in a straight path.
