INERT DEACTIVATED. *VERY RARE* This is a very rare Mexican 5.2mm (5.2x68) ball round for the 5.2.mm Montdragon Service Rifle, invented by Eduard Rubin of Switzerland, who created the .303 Rubin rimmed and rimless rounds used in trials of the early British Lee Metford service rifle. Rubin helped to develop this round and it was adopted for the Mexican Model 1894 Montdragon service rifle. The cartridge is unusual, being a small diameter jacketed bullet with a large volume straight sided rimless cartridge case with a cannelure approximately 16mm from the case neck. The cartridge has a piston fitted to the base of the bullet to aid velocity. The high volume cartridge case was developed to give high velocities with early inefficient smokeless propellants but with quick improvements smokeless powders rendering this design of cartridge case obsolete. This is a rare 5.2 mm (5.2x68) rimless round for the Model 1894 straight pull Montdragon Mexican service rifle made by S.I.G in Newhausen, Switzerland. The brass cartridge case is headstamped POLTE MAGDEBURG and has a unfired brass primer with a purple anulus. The cartridge case has a steeply angled shoulder and a short nickcrimping the round nosed jacketed bullet. See Cartridges, Volume 1 by F. Datig. The price for this rare 5.2mm Mondragon ball round for the Mondragon rifle includes U.K. delivery and no licence is required to possess this inert round in the UK if retained as part of a collection or display.
