Japanese Bore Cleaner?

Possibly someone has one of the japanese " de coppering" rounds in his collection and couldt share a foto ?
Did they produce them in 6,5mm, 7,7mm, 7,92mm, 12,7mm and 13,2mm ?
Any idea?

Nobody - nothing ???

There are some details of the 6.5mm Type 38 and 7.7mm Type 92 de-coppering rounds in Ken Elk’s book on Japanese ammunition.


Yes thank you. I have the book. Wouldt be nice to see some more real cartridges from collections.
