==== Even thinking just in “real-ish” terms: ====
* One 500 mm high-explosive shell could: - Flatten buildings - Destroy huge chunks of armored targets - Create blast radii easily tens or hundreds of meters across

In your monster scenario:
* Each shell can easily vaporize or obliterate many truck-sized monsters at once.
* With sci-fi upgrades, you could say: - 1 shell wipes thousands or even millions of them if it has a huge AOE or chain reaction.

So the key difference from 400 mm → 500 mm:
* Much more volume for: - Explosives - Exotic payloads - Fragmentation mass
* So per-shot kill count can go up drastically.
