Fool, with the low voltage given and its huge mass the momentum of the
armature beats that of most high power rifle bullets.

Railguns don't have an armature, they fire projectiles through the air,

The projectile is the armature, of the linear motor that in this case is
the railgun, Penisnino, most extraordinary ignoramus.

The muzzle energy of the very common 7.62x51mm NATO cartridge is

Weight of bullet is say 7g
Muzzle velocity is 300m/s
So ke is 0.5mv^2=0.5*.007*300^2=.0035*90000=3150J so okay

What is the muzzle energy of your low speed linear motor, crackpot?5
0.5*4000*1.5^2= 2000*2.25=4500J, Penisnino
which is greater than 3346J or 3150J or 1756J.
Quod erat demonstrandum!
More than those.
