why can’t we make an artillery minigun?

Question

So the concept started with the Gatling gun, the first rotating multi-barrel machine gun, and then was scaled up into the modern minigun. That was then scaled up to the 20mm Vulcan and 30mm Avenger autocannons.

Why can’t we scale it up even further with a multi-barrel rotating artillery cannon? One that shoots 3000 artillery rounds per minute and sends massive barrages of artillery?

Answer 1

There are multiple rocket launchers that do the job far better. Artillery fires the shell with a high angle and then comes down and explodes on the target firing multiple rounds that are large enough calibre to be useful as artillery would result in very poor accuracy for the later shots.
