wknitro,
sounds like you need to join German Gun Collectors Assn., you will find like minded people.BTW, they used a"," instead of a"." when writing numbers(or a / as skeetx said).I suggest orig.length (2.125")38-55 Starline cases for your 8x57R/360.They should lengthen a little when necking down, whereas 32-40 should shorten a little when fireforming.I'll bet it would make at least 0.003" difference.
