"That is partially correct. They used the same caliber bullets."
Bart, actually, that is completely correct.
The Japanese adopted THREE separate 7.7mm service cartridges.
One was rimless, and used in certain machine guns and the Type 99 rifle.
Another was semi-rimmed. Not 100% sure what it was used it.
And then there was the 7.7 Japanese rimmed, essentially a carbon copy of the .303 British in all of its rimmed glory.
It was used in the Japanese copies and variations of the Lewis and Vickers machine guns.
