Every shot produces:
* Hot gas
* Friction
* Barrel heating

At 1,000,000 rpm:
* Barrels would overheat almost instantly.
* Metal could soften, warp, or melt.
* You’d need extreme cooling (crazy barrel rotation, active cooling, exotic materials), and even then it’s milliseconds before things cook.

===== Let’s say the ammo is light, like 5 g per round: =====
* 1,000,000 rounds × 5 g = 5,000,000 g = 5,000 kg of ammo per minute
* That’s 5 tons of ammo every minute.

You’d need:
* Giant storage
* Huge mechanisms to feed it
* Something strong enough just to support that weight and recoil

===== Even with small rounds, firing 16,667 per second: =====
* The recoil force becomes enormous.
* Any platform (vehicle, mount, etc.) would need insane stabilization.
* A handheld or even small vehicle-mounted system is basically out of the question.

===== Even if you could: =====
* You’d obliterate your ammo instantly.
* Targets don’t usually need that many rounds.
* Accuracy and control would suffer badly—most shots would be wasted.

That’s why real-world systems usually stay in the thousands of rounds per minute range and focus on:
* Accuracy
* Reliability
* Controllable recoil
* Reasonable ammo usage
