These tiny, pocket pistol sized rounds were first designed by John Browning in 1905 for early automatic blow back pistols that did not have a breech locking mechanism to contain more powerful rounds. The bullet performs at about the same level as a rimfire 22 round, and the diameter of 7.1mm was the smallest that Browning could use that would still be able to accommodate a centrefire primer pocket. Round nosed, copper jacketed bullets were more reliable for feeding than greased lead bullets. The 25 ACP round became widespread with the release of the Colt Model 1908 Vest Pocket which was designed by Browning. Also known as the 6.35x16mm SR (semi-rimmed) or 6.35mm Browning. Price is for one round only. Please note inert rounds cannot travel with Royal mail or air mail, and must be shipped with courier.
