The Prechtl M98 Standard is manufactured according to the original measurements of the zivil Mauser 98.
All calibers which are larger than .30-06 are equipped with a larger civil Mauser magazine housing (originally manufactured by Mauser for 9,3x62 caliber, lengthened by us for 1,5 millimeters). The larger magazine housing can by extended with a Rigby II floor plate in order to allow an extra cartridge to be loaded into the magazine.
