From what I have heard "it was Gorings favorite caliber" is a figment of Harold Wolfs imagination! Anyway it is a thumper, I have used it in Namibia. Belongs to a german PH friend who is passionate about guns. Shot a very nice 41"+ gemsbok and a good springbok with it last year. His gun is a new rifle made by Johansen in germany I believe. He reloads for it using 404 brass.
