I'd get one before a .450/400.

I'd like to get a set of barrels for the .416 Rigby No.2 for my Tikka/Valmet U/O double rifle.

It's the same ballistics as the .500/416 NE.

Either would be nice as a chamberings for my Tikka 512.

One advantage is one could self regulate the barrels for either a 400 gr/410 gr load or the heavier .416 450 gr bullet. The latter bullet should out penetrate a 480 gr .458.

It would be cool to have a 250 to 300 gr load as a medium game cartridge. Even if it required a second scope sighted in only for one barrel.

A side by side .416 Rigby No.2 would be nice if I had unlimited funds!

The downside of a .500/416 NE, .416 No.2 and even a .375 V-C is the recoil. The recoil is approaching .450 or .470 NE. Given that, which is more effective?

IMO the .416 Rigby No.2 Rimmed success is guaranteed. If only because Rigby offers it in their optional line up. And ammunition can be sourced. These makers do not need to sell dozens of rifles per year for the cartridge to be a lasting success.

BTW I discussed with Jerome Lanoue, a master gunsmith at Rigbys. He was previously at Verney-Carron. Jerome said the .416 Rigby No.2 is not a proprietary cartridge. So if so, other gunmakers and gunsmiths could chamber rifles for it.
