The case is rimmed and very slightly necked. The bullet is enclosed inside the case. The necking merely serves to retain the bullet and also acts as a lead-in for the cartridge, as it is forced forward to enter the rear end of the revolver barrel. The case may be of brass or steel. The actual shape of the necking or taper at the front of the case appears to depend very much upon the ideas of the individual makers; some have a straight taper, others may be found with a slight shoulder. The standard service bullet
is lead cored and nickel jacketed, with a flat tip. The bullet may be additionally retained in place by punching into the case in two opposed places. This cartridge was developed by Leon Nagant, a Belgian gunsmith, in the early 1890s to suit a gas seal revolver he had designed. The gas seal element involved moving the cylinder forward, so that the chamber about to be fired enclosed the rear of the revolver barrel and the mouth of the cartridge actually entered the barrel. On firing, the case mouth opened out to form the gas seal. This, in theory, obviated the usual leak of gas at the cylinder/barrel faces and improved velocity. The actual gain is small and scarcely warrants the mechanical complication of the design. Nevertheless, the Russian Army adopted the design in 1895 and the weapon was manufactured until 1945. Large numbers still exist in reserve stocks and paramilitary hands, and in addition there is a number of target revolvers of gas seal pattern still manufactured in Russia and the Czech Republic. Applications include russian/Soviet Nagant Model 1895 revolver.
