Can an unwanted heavy shell go back to the ready rack?

Could a turret put an unwanted shell back into its ready rack?

Usually not; a heavy shell already in the hoist would need lifting gear, so the turret normally fires it before changing ammunition type.

A viewer asks whether an unwanted shell could simply be returned to ready stowage. A capital-caliber projectile would need a crane or equivalent lifting machinery to leave the hoist. The confined loading position generally does not contain equipment for that reverse movement. In practice, the turret fires the rounds already committed to the path and changes ammunition type with the following rounds.
