Germany’s Rifle Round in Two World Wars
The 7.92x57mm Mauser – better known in Britain as the 8mm Mauser – was adopted by the German army in its pointed-bullet form in 1905. It went on to arm the Gewehr 98 in the First World War and the Karabiner 98k, MG 34 and MG 42 in the Second, as well as being used by many other armies between the wars.
It is still a respected sporting and hunting round in Europe today, and a favourite with collectors of military rifles.
The Keyring
Each keyring starts as a once-fired 7.92×57 brass case. It is cleaned and polished, resized to full length and fitted with a seated bullet, then finished with a 25mm split ring. At around 82 mm long it is one of the larger rifle keyrings we make.
