How 9.2-inch shells compare with 8-inch shells

How would 9.2-inch shells compare with 8-inch guns in a bombardment role?

They are larger, carry more explosive, and generally offer longer range in a comparable mounting.

The 9.2-inch round is materially larger than an 8-inch shell. It carries more explosive and, in an otherwise comparable weapon, normally reaches farther. Contemporary examples must be compared at a similar technological standard because later 8-inch guns benefited from upgrades never applied to an out-of-service 9.2-inch system. The larger calibre offers a real gain in range and destructive effect rather than a merely nominal increase.
