All in all, I think a good article fairly written. I do agree that if Rem had of loaded to Rigby performance or slightly under the 416 Rem would be more widely used in Africa and could certainly be used in a slimer rifle than the Rigby requires. That is to get 4 or 5 in a double stack mag.

The main reasons I went with the 416 Rigby were, Cartridge availability in Africa, more so than the 416 Rem. I could get an affordable - for me - rifle which I could not with the 404J.

To me the Rigby has a fair bit of recoil and the Rem a bit less. If you can handle the recoil, there is no reason either can not be used to 400 mts on plains game if the shooter is capable.

The 416 Ruger ran into overpressure issues when it first can out, this because they were trying to match Rigby performance. Turns out if your happy with 2250 fps and not 2400 fps then the Ruger is fine and from what I can tell by reading the 2250fps MV does the job very well.
