The CZ 550 Classic (American) Magnum is now available here in Australia and I have decided to get one in .375 H&H as a companion for the Safari Magnum in .458 Lott which I have just bought from one of our members.

While it is in the 'smith getting the normal things done I am thinking of having it rechambered to .375 Wby Magnum.

Is there any real advantage in having this conversion done?
