Utter nonsense, crackpot. Railguns don't have an armature, they fire projectiles through the air, crackpot. The muzzle energy of the very common 7.62x51mm NATO cartridge is typically around 3,346 J. The muzzle energy of the very common 5.56x45mm NATO cartridge is typically around 1756 J. What is the muzzle energy of your low speed linear motor, crackpot? Do you even know how to mesasure muzzle energy, crackpot?
