Well the 404 is older than the 416, and has done more heavy lifting in Africa whilst not being placed on a pedestal by Ruark..416 Rigby
History, nostalgia.
Definitely.416 has a better case design in my opinion.
This. Vastly better ammo and components options.I sold my .416Rigby to start a .404J build.
If I had to do it over again I would keep the .416Rigby - much better bullet choices and brass availability.
That's ok too. The double rifle's successes were mostly based on 2150fps.I appreciate the replies. I find I’m somewhat recoil shy so probably wouldn’t load either past about 2200 fps.
