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 for Reimer Johannsen GmbH who loaded the cases for use in his Johannsen Express Rifles and the second specimen by Horneber with their own headstamp.
