Could Kongo use British 14-inch ammunition?

Could the Kongo class use British 14-inch ammunition, or vice versa?

Possibly, because the guns shared a Vickers lineage, but the heavier British shell might exceed the Japanese handling system's intended load.

Kongo's 14-inch armament came from a British Vickers design closely related to later British weapons of the same nominal calibre. That common origin makes ammunition interchange plausible rather than absurd. The British shell discussed here was roughly thirty to forty kilograms heavier than the Japanese projectile. The limiting issue would therefore be whether Kongo's shell hoists and handling machinery could safely manage the additional weight, not merely whether the round fitted the bore.
