The .300 Holland & Holland magnum is a very beautiful and traditional calibre .
His Royal Excellence , the Maharajah of Jodhpur used to own 1 of them in his armoury.... an original Best Grade bolt rifle , built on a pre war Mauser 98 action by Holland & Holland, themselves . He would use it for hunting sambhur deer and Wild Boars .
I always wished that some day... I would have at least 1 of my clients bring a rifle chambered in .300 Holland & Holland magnum calibre to India for shikar . However , it was sadly never to be . All of my clients would either bring .300 Winchester magnum or .300 Weatherby magnum calibre rifles .
By the way ... perhaps, this may interest you . It is the description of the .300 Holland & Holland magnum calibre rifles from my soft copy of Holland & Holland's 1958 catalogue .
