11mm Pin fire
The 11x17 revolver cartridge is a natural development from the 11 mm pin-fire cartridge. It is not a development in performance, only a leap in technology as the center fire were developed, and was a much better cartridge type that is safer to use and quicker to load.
The Earliest cartridges, the m/71 were produced by Jules Gevelot from Paris, and it has a two part primer, a 13 gr projectiles and is loaded with 0,85 gr of powder. The parts in a m/71 cartridges consists of: outer case, bottom plate, inner case, pin, paper wadding, percussion cap. It is not know for me for how long time this cartridge were imported, or in what numbers.
The Swedish made m/71 cartridges were of the same specification, even if the projectiles weight is specified to 13,2 gram. It is not know to me when Sweden started the local production.
The 11 mm m/87 cartridges is produced in the modern weld-less design.
The first revolver to be adopted for the 11x17 center fire cartridge is the Lefaucheux – manufactured by August Francotte of Liège, designated m/1871.
The second revolver to use the cartridge is the converted m/1863 pin-fire revolver, renamed m/1863-79.
The third revolver is the M/84 revolver for the marine. Yes, note the large "M" in the designation used for the marine, a kind of a separator between the marine and the rest of the troops. This revolver is specified as of 11,4 mm caliber, and there is a established round to be found in Marinmuseum in Stockholm, but there is no proof that it was actually bought in at any larger numbers for the use in the marine.
Troublesome comments can be found of the quality of the 11 mm round, published in the "Kongl. Krigsvetenskaps-akademiens tidskrift, 56 utgåvan Juni 1888"
At the trials in 1884 for the evaluation of the to become 7,5 mm revolver m/1887, revolvers m/1871 were used as comparison. Here the "Kronprinsens husarregemente" reports of a failure rate of 20 cartridges out of 240 fired rounds. Also "Ridskolan å Strömsholm" reported a high failure rate for the 11 mm cartridges used.
How the m/71 cartridges were packed seems to be buried in history. I have not seen any pictures or written sources of it yet.
The Swedish m/87 cartridges is packed in paper, 6 rounds per package. This package is called a "bundt". The " bundt" is not labeled or in any other ways marked.
