Various Nitro Express, 505 Gibbs, 500 Jeffery's are common chamber for double rifles. They are high dollar. They are all custom. Haven't heard of any major production of any of these calibers.
I think the Nitro Express cartridges are rimmed like a 30-30. 470 NE, 500 NE, 505 Gibbs are about 10-20$ a round.
I picked up a Norma PH (professional hunter) brochure. Pretty awesome energy of these big calibers. Gives really good ballistic comparison of the big calibers. 375H&H 350gr is the smallest in the booklet.
I've seen a slug removed from a bull moose that was 500gr .458 Win Mag. Big slug. But just the bottom end of these double rifles.
You can get a CZ 550 in 458 Lott for ~900$. It shoots .458 Win Mag with about 300 extra fps. Of course there is the 460 Weatherby.
Around Christmas, there was a 700 H&H at Cabela's in the gun room.
