11mm Pin fire
The 7,5mm Nagant ammunition were used for the Nagant revolver m/87, a
nicely looking officer’s handgun. It was in regular service from 1887 to 1907,
when pistol m/07 replaced it. It lived a life after that in the total defense
and were used in the local defense during WW2. It were also used for many years to train and test dogs, firing a star crimped blank.
When the revolver were assigned in 1887 it was regarded as equipped with a weak caliber. This was due to a total rethinking, going from a large 11mm 13,2 gram bullet performing to 160 meters per second (or even down to 120 meters per second v0) to a sleek 7,5 mm 6,7 gram bullet performing 220 meters per second. The plus side were:
-The revolver could be made considerably smaller and handier.
-The shooting range were extended from a maximum of about 110 meters to 170 meters with a much better trajectory within the intended range of 30-50 meters.
-Delivering a considerably better precision.
The revolver were not only considered accurate, it were also easy to clean. One good thing was that the revolver were not getting as dirty at firing as the previous revolver, and lifgardet till häst reported that they in the trials of 1884 had fired up to 75 shots without cleaning the revolver, and still received accuracy and functionality.
The penetrating abilities were considered to be impressive, particularly in wood. The ammunition is really nice to fire, the feeling is close to that of a modern .22LR revolver.
The ammunition has developed slightly during the years.
The Swiss produced original ammunition were used in the trials of 1884, but at the introduction of the revolver a local production were started up at the Marieberg factory.
The first type, m/87 used a paper patched led projectile and were loaded with black powder. The paper patch were used to lessen the led fouling in the barrel.
A mantled ammunition m/98 with smokeless powder were developed and used for a short period. As it had issues with the shelf life it was discontinued, and the paper patched m/87 were to take over again.
The third one were evolved with wax filled rills and smokeless powder.
There were two types of blank ammunition.
The normal type were with a wooden projectile dyed in purple. I guess you had to be really careful when using it as no blank firing device were available.
The star crimped blank were intended for the training of dogs.
There is also blanks to be found, that is loaded in unaltered cases, without a projectile but with a seal of black or white hard varnish or resembling material. I have not been able to figure out how these fit into history. They might be "homemade", or done by an armorer, or in some other reason.
As late as in 1941 there were an order for 1.000.000 rounds ordered from Suhl to a total value of 120.000 sek
