As there was a rimless 6.5x27 too, meant for repeaters, the monicker "Einzellader" = single shot made sense for the rimmed 6.5x27R. Remember, before WW1 the now German cartridge designations (nominal caliber)x (case length)and "R" were not yet in common use. Cartridges were often called this way: 27/6,5 mit Rand (= 6.5x27R) or M88/9mm mit Rand (= 9x57R). Relating the name "6.5x27R Einzellader" to the Einzelladungen once available for the 8.15x46R shows insufficient familiarity with the German language. Likely Frank C. Barnes in Cartridges of the World started this misunderstanding and every other expert like Dixon simply copied it from this "authority".
