So long as you have a means to solve the Powerpower supply and power delivery, then yes. This is very feasible.
Solid projectiles have a number of benefits that Energyenergy-type weapons don't have - mainly revolving around the need to dissipate all that Kinetickinetic energy.
Now, sure, a Laserlaser has a lot of energy to dissipate too, but with a big enough Heat Sinkheatsink or Shieldshield or thing, it's just absorbing energy.
Whereas with a solid projectile, you have Newton's lawsLaws of Motion - Equalan equal and opposite reaction e.g. Knockbackknockback/Staggerstagger.
Even in the real world, wherewhen someone wearing Body Armourbody armour gets shot by a conventional firearm -, they still feel it, scale it. Scale that up to the speedsenergies a Coil Guncoil gun could achieve and we are talking some serious down-range effects even if the round doesn't penetrate
Then if you are using physical armor to stop it, you have to deal with things like Spallingspalling, etc.
