In naval artillery "caliber" refers to how many bores long the barrel is from breech to muzzle. Arguably, part of the turret assembly weight should be allocated to elevation gear and not impact reload time since the shell and powder loads don't inherently change.
Guns produced close together generally have the same, or similar, elevation rates despite being of different bores/calibers; see British 14"/45 M2, 4, & 5 vs 13.5"/45 M5 L & H, also USN 14"/50 M7, 11, & B vs 14"/45 M8, 9, 10, & 12. (navweaps.com)
If a given nation can produce a range of guns in 9" bore during a given year then the calibers of those guns should all have close elevation rates.
