I only skimmed the article.

I wanted a Chatfield-Taylor .416 once upon a time in a takedown Winchester M70. Along with 7 mm RembMag and .338 Win Mag barrels.

Was going to get Brian Harre of NZ to make it for me. An outfitter whonwas getting into gunmzking. Later made Mauser 98 actions.

Ot interested in modern pretenders. Only the .416 Rigby if a bolt action.

But I would go for a .500/416 Nitro Express or a .416 Rigby No.2 Rimmed. The criteria would be which has the longevity. Which would have supplies? .500 brass could be used for the .500/416. And which has more street appeal?

Unless a lotto win happens, no rising b bite side by side. But a Valet/Tikka U/O set of DR barrels might be possible. Self regulation barrels and qd scope or qd red dot!

A 450 gr .416 at say 2100 to 2200 fps? Penetrate and results similar to a .458 480 gr.

No need for any .416 bolt action if one already has a .404 Jeffery. Even more traditional.

I didn't read the article. All of them do the same job. All will have the same results at the animal end. It just depends on whether one likes classic traditional choices or likes the flash new pretender wannabe copies!
