The 8.15x50R M Target as well as the 8.15x52R M Target was only listed in the 1900 RWS/Utendoerffer catalogue and has a gradual ‘b’ type shoulder.   

The exact date of introduction of the 8.15x46,5R Frohn is not clear, but is was during the early 1890’s and it became one of the most popular target cartridges of its era. It was offered by almost all manufacturers of the era. (Dixon Ref. GSP6)

During the late 1800’s to the beginning of the 20th century competing German manufacturers produced cartridges that were very similar in dimensions but which were not interchangeable. Since the mid 1880’s efforts were made to standardise the dimensions of these...

This is the rimless version of the 8x75RS Behr and was introduced just after it during 1907 with the ‘S’ indicating loading with the .323” bullet but never gained any widespread popularity. The specimen below with EXPERT headstamp was loaded around 2000 by Horneber...

The 8x75RS Behr was developed by DWM for Behrs Weapon Works of Suhl (Simson) using the 9.3x74R case that was necked to 8mm, (in this case for the S-type or .323” bullet). This version was the first to be produced and was the only one of these four types shown in the...

Someone tried to load this with a shotgun primer.

     The bottom version is a reproduction for collectors. It was manufactured in South Africa by OPM.

The 8x72R Brenneke was a popular European sporting caliber designed for drilling rifles was based on the English 360 Express case. It was originally listed as the 8.1x72B (for Brenneke) and believed to have been first produced by RWS/Utendoerffer with the "D.R.G.M....

This necked Collath case is also based on the English 360 case type and should not be confused with the tapered 8x72R Brenneke (W12) or 8.2x72R Austrian (GSP23) '360' types. This is a scarce cartridge but is known with both the earlier Collath hs and the later 'TESCO'...

Most likely produced by RWS during the period 1898-1909. Not much is known at the moment on the history of the Nimrod cartridges   

This is the rimmed version of the 8x68 Magnum. There are very few, if any original specimens known. An RWS headstamped version has been reported but no actual specimen has been seen yet. There is also an unheadstamped version that also seems rare. The version below is...

Developed during the mid-1930’s as a more powerful 8mm version than the existing 8x64 or 8x75. Power is about on par with the 375 H&H and it might also have been a German attempt to compete with the medium/large British calibers for African Hunting. (Dixon Ref....

The 8x64S was designed in 1912 as a necked-up version of the 30-06 cartridge and the S (.323) version was believed to be the first rimless Brenneke loading. It was originally conceived as a military cartridge but was not adopted and Brenneke shifted the focus to a...

This is the "J" version of the Brenneke cartridge and designed for the civilian market. It is basically and extended version of the 8x57 This was the prototype loading from existing 7X64 Brenneke cases This was an 8X65R case with the rim turned down.

     Case length is too short for it to be a 8x65R Vierordt (EXP21) Measurements: Bullet:   8.01mm Mouth:  8.76mm Neck Dia:  8.82mm Shoulder Dia: 10.00mm Base:   11.00mm Rim:   12.33mm Neck length: ...

This is one of two Vierordt versions, the other being the 8x65R and are based on the 360 Express case. This was a proprietary load for Vierordt & Co, Germany        

     This was a civilian prototype that led to the development of two standard factory cartridges, namely the 308 Norma Magnum and the 358 Norma Magnum. Developed by NILS KVALE in 1949, the idea was to create a "magnum" rifle by way of a simple...

This might have been an experimental design based on the 11mm Mauser case.   

  This cartridge was marked "8X60RS MAGNUM BOMBE" - There was a article on this on Guy Hildebrand's site - Sept 2003. This one has a knurled rim, so most likely some proof round?

The rimmed version of the 8x60S is believed to have been introduced after the rimless version with the earliest DWM cases known from around 1928. (Dixon Ref W39)          

The 8x60 with S bullet (.323”) first appeared in the 1928 RWS and 1930 DWM catalogues and it seems therefore that the J (.318”) bullet preceded the S offering, as the smaller diameter loadings were already offered in the 1924 RWS catalogue. After WW1 the possession of...

Developed by the late Horst Grillmayer and is based on the 376 Steyr case necked down.   

Relatively rare cartridge dating from around 1898-99 onwards. Was produced by various companies but in all probability did not survive post WW1. (Dixon Ref. GSP29)   

It is believed that Collath first produced this cartridge in the early 1890's for use in Collath rifles that were converted from Needlefire to Centre Fire. It was once a popular cartridge, as the name implies, was based on the English '.360' case and was used for both...
