Battleship gun-barrel life depends on charge and powder

A rough barrel-life figure of 750 to 800 rounds hides major variation from charge strength, propellant chemistry, and inspection results.

Question

How many rounds could a battleship gun barrel fire before replacement?

Short answer

Roughly 750 to 800 is a broad guide, but charge, powder, and inspection condition make the real answer highly variable.

Notes

About three full magazine discharges provides a broad reference, roughly 750 to 800 shots. Full and reduced charges produce different amounts of wear. Changes in powder can extend barrel life even at full charge, while other powders cause more damage. Barrels therefore need careful inspection after action, and a fixed round count cannot settle their condition.
