Okay, now it’s a 1,000,000 rpm, 400 mm caliber, infinite-everything monster gun fighting a quadrillion truck-sized monsters. Got it 😄

Let’s translate what 400 mm means first, then see what changes.

==== 400 mm = 40 cm = almost half a meter wide. ====

That’s not rifle ammo anymore. That’s:
* Bigger than most naval battleship guns (those are ~356–460 mm).
* Each round is the size of a small car tire or large oil drum and could weigh hundreds of kilos.

Now imagine firing 16,667 of those every second.

Even in a sci-fi setting, that’s beyond absurd.

==== A single 400 mm shell (in real life) can: ====
* Level buildings
* Punch through heavy armor
* Create a big blast radius

In your setup, we can assume each round is at least:
* High-explosive, or
* Something even nastier (plasma, antimatter, whatever)

So:
* 1 shot can probably obliterate many truck-sized monsters if they’re near each other.
* You don’t need a 1:1 ratio of shots to monsters anymore.
* Each second you’re throwing out tens of thousands of giant explosions.

That’s a sky full of city-killers every second.

==== You said earlier: ====
* Recoil can be handled ✅
* Ammo is infinite ✅
* Durability is infinite ✅
* Spent casings turn back into energy ✅

So we ignore:
* Barrels melting
* Frames shattering
* Ammo ships
* Logistics, etc.

The remaining practical limits now are:
# Coverage – can you hit enough of the swarm fast enough?
# Overkill – are you wasting insane firepower on single targets?
# Friendly space – is there anywhere safe near this gun?

==== Previously, with small bullets, you needed hundreds of thousands of years of perfect shooting. ====

Now, with 400 mm shells that:
* Can destroy dozens or hundreds of monsters per shot (via blast radius, fragmentation, shockwave),

your kill rate could go way up.

Example, just as a rough idea:
* Each shell kills 1,000 monsters (very conservative for that size, honestly).
* 16,667 shots/sec × 1,000 kills/shot = 1.67 × 10⁷ monsters/sec
* Quadrillion monsters = 10¹⁵

Time to kill them all:

10151.67×107≈6×107 seconds≈2 years\frac{10^{15}}{1.67 \times 10^7} \approx 6 \times 10^7 \text{ seconds} \approx 2 \text{ years}1.67×1071015≈6×107 seconds≈2 years
So with really big AOE rounds, you’ve gone from:
* 190,000 years → to maybe a couple of years of nonstop bombardment.

If each shell is even nastier (kills 10,000 or 100,000 at once), you’re down to months or weeks of firing.

So yeah: 400 mm helps a LOT, because now every round is like a small apocalypse.

==== With 400 mm, 1M rpm, and infinite runtime: ====
* The terrain is gone. Craters on craters on craters.
* The atmosphere is probably: - Full of dust - On fire - Shockwave-blasted constantly
* Any planet you’re fighting on: - Is getting pummeled harder than any known bombardment, continuously. - Could end up partially vaporized or tectonically wrecked.

You’re not just fighting the swarm; you’re basically terraforming-by-destruction.

==== With a 400 mm, 1M rpm god-gun and your cheats: ====
* It actually starts to seem plausible (in a sci-fi sense) to wipe out a quadrillion truck-sized monsters eventually, because: - Each shot is massively destructive. - Rate of fire is insane. - You never run out of ammo or barrel life.

But the cost is:
* The entire battlefield (maybe the whole planet) is annihilated in the process.
* You haven’t built a “weapon” anymore, you’ve built a continuous extinction event machine.

If you want to push it further, we can imagine:
* What the monsters would need (shields, regeneration, teleportation) to survive that kind of artillery spam.
