"...popularity of the .416 Ruger is fading, whereas the .416 Rem is growing."
Dirt: What fact do you base that statement on?
"I recommended the .416 Rem. mostly for the above reason and brass availability.."
In my experience I have found Hornady 416 Ruger brass very available. 416 Remington brass is made by Norma, Remington, Hornady, Bertram, Quality and Jamison. There are more different head stamped 416 Mag brass but I am unsure as to who manufactures the brass. The one thing I am sure of is that 416 Remington ammunition is more available in Africa then 416 Ruger despite what the Hornady marketing department claims.
The water case capacity of the 416 Ruger is 75.8 grains and the 416 Remington 80.0 grains. The Ruger fits into a long action at 3.34" OAL but the Remington needs a magnum length action at 3.6" OAL
The 400 grain bullet maximum velocity using Nosler loading data is 2424 fps for the Ruger and 2503 fps for the Remington.
