==== At 1% c, 500 mm shells don’t just “hit” things: ====
* They vaporize and pulverize anything solid in the impact zone.
* Shockwaves travel through the target and beyond like a mini meteor strike.
* Even if your monsters are insanely tough: - Each shot is more than enough to completely erase one truck-sized monster and anything near it. - Realistically, one impact would obliterate dozens to thousands of them if they’re packed in a swarm.

For a quadrillion monsters:
* The problem isn’t “can you kill one?”
* It’s “can you sweep enough volume of space fast enough?”

With this level of kinetic energy, the answer is basically yes, if they’re anywhere near a planet or clustered.
