Help me ID this shell please

[Sardaukar]

A friend of mine found this shell at his family cabin in the woods.

It's about the size of a .357 magnum, with a slight taper. The headstamp reads D/|\C '2 C VI 05

From what I could find the D/|\C headstamp was used by the Dominion Cartridge company in Québec City around 1900. The broad arrow make me think it's surplus.

Does anyone know what this is?

i was thinking, not enough taper, maybe a brass .410 cartridge, ?

Too short, the .410 was the length of the .303 cartridge case.
