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)          

  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?

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

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...

     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 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

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...

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 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'...

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...

Someone tried to load this with a shotgun primer.

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...

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 8.2x72R Express can be mistaken for the 8x72R Brenneke, however it was not made by any German manufacturers and the bullet diameter is larger, and the case has a different taper. This was a popular cartridge in Czechoslovakia and loaded by them up to about 1950....

New development by Blaser and loaded for them by Norma that was announced at the 2019 IWA show in Germany and based on the 404 Jeffery case albeit with a slightly rebated rim.   

This is a development from around 2008 although there is not very much info available on this at the moment.
