Could large battleship autoloaders reload at more elevation angles than manually loaded guns?
Short answerPotentially, but the elevation envelope depends on the turret design and on how much weight and space are devoted to the loading machinery.
NotesManually loaded guns were not always restricted to one exact loading angle. Many systems could load within a limited elevation range. Automation can extend that envelope if designers provide enough travel and machinery. The added equipment consumes space and weight, so the gain is not free. Each turret's allowable loading angle is a design choice rather than a universal property of autoloaders.
