Mixed ammunition burdens encouraged gun standardization

Did multiple gun calibers make ammunition supply aboard pre-dreadnoughts difficult?

Yes; it was a recurring problem and one reason navies moved toward more standardized armament.

An audience question points to the difficulty of carrying enough ammunition for several different gun calibers. Mixed batteries frequently created a supply problem. Each caliber required distinct shells, propellant, storage, and handling arrangements within the same hull. Those burdens became one of the pressures encouraging greater armament standardization.
