Feasibility of Relativistic Artillery / Kill Vehicles

As far as it is known, Relativistic Kill Vehicles are a common weapon in science fiction and are rendered as powerful as nukes just due to their kinetic energy alone, a finite mass being propelled at a portion of lightspeed.

However, one thing that has never been questioned is its feasibility, and thus I ask if it is possible to construct such a weapon.

Rules:

• Any percentage of lightspeed is fine, as long as it is above 1% lightspeed.
• The length and the size of the gun is up to you. Any resource is also fine, maybe even slightly theoretical, as long as it is not complete Unobtainium or Handwavium.
• The bullet should not have any rockets, and only a starting spark or propellant is allowed. Or magnetic materials for the bullets. Having a rocket function makes it more of a Relativistic Missile instead of a Relativistic Gun, which is what I am more looking for.
