10 rounds a minute from a 152MM gun that's rapid, wonder how long it could realistically keep that up. The loader would not be the issue I would guess overheating & wrecking the barrel would be the issue.
Then there's the logistics of actually supplying the ammo, they are big shells.

Changing tack a bit I do wonder how much of this stuff will actually make it into mainstream service.
Russia seem to be waving the flag saying look we can still make good stuff.
My guess though with perhaps the exception of the Armata platform most will see a handful to 30 odd produced & assigned somewhere.
