The 10,93x57R was listed as case #155 in the 1886 Lorenz export catalogue as a Swedish case. It was also listed in the Egestorff catalogue up to 1901. (Dixon Ref SC12)    

This large cartridge was a Sporting rather than a Target cartridge and is uncommon. It was introduced by DWM as case #495  (c1905 - not being shown in the 1904 catalog). The case uses a raised base with MB dimensions but has a tapered body unlike other MB types....

This is the rimmed version of the 10.75x68 Mauser. There is not any other info known except for an RWS case drawing dating from 1926.      

Very popular sporting cartridge in Europe and Africa and in all probability developed around 1907 – 1908. There is an Obernforf Mauser rifle chambered for the 10.75x68 in South African that has a date stamp of 1908, so it would seem an accurate assumption of the...

This is a rare cartridge that is often confused with the 10.75x65R Grundig, but as can be seen, this one has slightly smaller dimensions and is necked whereas the Grundig has a straight case. It appears to look like a slightly necked version of the 11x65R Collath....

This cartridge was likely the first of the rimless cartridges based on the G (Gründig) case type with a base of 12.55mm. It definitely precedes the 10.75x68 (M58) which is a longer neck version of this 63mm case version and is also likely to be introduced prior to the...

The 10.75x60.5R LV2 uses a base diameter of 13.6-13.7mm which is the same as the 10.15x60.5R LV4 (SC23) but has a 0.5mm greater diameter bullet than that cartridge. It was listed in the 1900 RWS catlogue, but no other references has been seen until the 1922 Hagen...

According to Dixon, there is considerable debate over the origins and purposes of both this and the rimmed equivalent (A42). The RWS '10.75x52 G' and the Austrian '10.75x52 Mannlicher' appear to be the same cartridge. Both have a 12.5-12.6mm head which is used by both...

This cartridge was produced by Lorenz, Utendoerffer and Roth, but the three may be different. No Lorenz versions have been examined yet and the Utendoerffer version is the least rare of the three.   

The round was listed in the RWS catalogue around 1900 where it was listed a the 10.45x82,5R “No. 400”. This is not the German equivalent of the English 400 3¼in Black Powder Express produced by RWS/Utendoerffer, as the dimensions are slightly different on the base....

This is a shortened version of the 10.45x82R Express (EXP 50).   

The 500/416 was introduced around 1997 by Wolfgang Romey together with Krieghoff and was based on the 500 NE necked to 416 with the intention of giving traditional 416 Rigby ballistics in a double rifle. (Dixon Ref. W90)  

Relatively new European Sporting cartridge, no other info yet   

This cartridge was produced for IMPALA EUROPA of Guntramsdorf, Austria. It was introduced at the "Jagd und Hund" trade fare in Dortmund, Germany in Feb 2008. It is based on the 30-06 case necked up to 10.4mm   

This one of three variations of the 10.4x47R MS (flat base) case. This cartridge was described by RWS/Utendoerffer as the 10.5x47R Beaumont and it became popular in Switzerland where it is better known as the 10.4x47R Vetterli M.35 as can be seen on the box label,...

This cartridge seems a bit of a mystery in the sense that it has a very unusual semi-rimmed case with the appearance of a raised base due to it having a very thin rim. It has the same base diameter as the 7.5x53 Schmidt-Rubin (SW20). It might have been used for both...
