I have started to plan a rifle project in 404 Jeffery. I got a battered, old Brno ZKK 602 in 375 H&H some time ago. Both the barrel, and the montecarlo stock is not to my liking, so I have to build something more appealing.
I have been looking at the prewar Rigbys in 416, as well as Mr.Dorleacs 404 Jeffery-build. In my eyes,the styling of these rifles looks as a biggame rifle should.

Does anyone have any input on measurements of a barrel for 404Jeffery?
For starters I have been thinking of a barrel length of 24", and a muzzle diameter om 0.750".
