I have a 416 Rigby, just broke down my long time 416 Rem, and I am in the process of building a 416 Ultra (just got the barrel).
First off there is no such thing as a bad 416!
All of them have fantastic smashing power for any North American animal.
The 416 Rem is a great choice....Certainly the most sensible. With a 350 grain X it shoots plenty flat too. Why did I take mine down?....Boredom.

Case capacity could be better and pressure lower, but if you load your own there is no reason to have a pressure issue.
The 416 Rigby is one of the greatest rounds in history. Problem is I have shot Remington rifles for so long anything else is well..Something foreign and something unfamiliar. Magnum actions are big, heavy, and quite frankly clunky...I own a few and still like them, just not when the going is serious.
If I grew up shooting Brnos I am sure a Remington would feel all wrong.
The 416 Ultra is my attempt at a compromise. In terms of case capacity I think it is perfect for the 416.
The 416 Ruger would be similar to the Remington. Might be the way to go if you like the Ruger it comes in.
I really like my 375 Ultra. As Boomer suggested it really has closed the gap between 375 and 416.
For North American hunting it is a better choice.
Recoil in all of these is the real deal....You've been warned!
