What's this?!? No powder you say? No primers? No rail needed? No brass too? Damn, I must have one.

I promise you'll never see this available for purchase in our life time, and I mean anyone breathing now.

There’s a company(gun shop) over here in powder springs that has a couple of EMRail guns already up and running…

It's not that complicated.
More issues with the proper projectiles

 

[pokus]

The evolution of electromagnetic rail (usually long rail big projectile and huge power) and coil (smaller and more portable) guns is rapidly progressing because more affordable safe practical components - rechargeable batteries boards and hv capacitors . They are cool but not yet a practical or reasonable alternative to powder actuated devices because of the lack of complexity and the stored power equation in a chambered barrel and cartridge. Super High Output batteries like Milwaukees, SMRs and microreactors will make rail coil and laser guns more practical very soon.
