==== With: ====
* 500 mm shells
* 1% c velocity
* Gigantic KE per shot
* Huge blast radius per impact
* Insane sustained rate

You now have:
* A weapon that can realistically sweep enormous volumes of space/ground per second.
* If the monsters are: - Bound to one world, or - Clustered around a system

Your gun is basically:

: 

The real limiting factor now is geometry and line of sight, not raw damage:
* Can you see them?
* Can you track them?
* Can you aim fast enough?
* Are they spread across a galaxy or all on one world?

But in terms of per-shot lethality, you’re way, way, WAY past overkill for truck-sized things.

===== With 500 mm shells going 1% the speed of light: =====
* Each shot hits like a 500+ kiloton nuclear bomb.
* You fire 16,667 of those per second.
* Your gun outputs energy like a small star.
* Any truck-sized monster is beyond dead; whole regions get wiped per impact.
* The planet or battlefield will absolutely not survive the fight.

At this point, your “gun vs swarm” setup is basically:

: 

If you want, next we can flip it and ask:
'' What would those monsters have to be like (regeneration, shields, physics hacks) to survive ''this* thing?
