The Devisme cartridges were some of the earliest centerfire metric metallic
rounds developed. They are inside primed.

They were the idea of the 1860's Paris gunmaker, L.S. Devisme who designed
a number of revolvers and developed the ammunition for them. Similar designs
are also found in 7mm and 11mm calibers.

This design achieved no commercial success outside of France and consequently
the rounds are scarce.

Note the construction of the priming system which consists of a copper cup
containing the priming composition which is sandwiched between the brass case
and an internal brass component which acts as the anvil and contains the flash
hole. This makes them difficult to identify from rimfire cartridges when only
looking at the exterior.

The round is very distinguishable as the headstamp is a raised
‘GG (monogram) D. 9 M/M’

NOTE: One visitor reported: "The cartridge posted is in fact a 9
mm Dumonthier used in walking sticks guns (cannes)and blowpipe guns (sarbacanes).
This is an old mistake perpetuated by Erlmeier-Brandt."
