The .400 will use .411" bullets, and is based on the .375 H&H case; load is 400 grains at 2,375 fps. The .465 H&H will use the same bullets as the .465 Nitro Express, and is based on the .460 Weatherby case; the load is 480 grains at 2,375 fps. Both cases are belted magnums, and the taper will remind you of the .375 H&H. I have never been a subscriber to the "belts are bad" school, so I hope I don't diaappoint you by not whacking these designs.
I asked Russell if the these two rounds could be considered a .500/.450 Nitro Express and a .500/.465 NE for magazine rifles, and he allowed as how that was a fair comparison.
The had three prototype rifles in the booth; actions were Mauser M98s still in the white. Rifle will require one year after order, and will sell in the $23,000 range.
Ammunition will be available in about 4 months for the .400, and a couple of months after that for the .465. Wolfgang Romey will sell ammunition, and will make drawings available to the trade (as I understood it).

The 400 H&H is just a goofy re-do of the 404 jeffery.
The 465 H&H offers no advantage over the 458 Lott.
Both new H&H cartridges have too much slope in the shoulder by modern standards.
H&H is just trying to be different, but should have opened up their minds to the advances in cartridge design that have occurred over the past 90 years.
So don't buy one! <--- humor
Take a read in Taylor's book on the .500/.400 and .500/.465; the originals were doing an excellent job -- these cartridges will too.
We don't buy rifles for what is "best" anyway!...jim dodd

"if you are to busy to

For example, the long sloping shoulder tends to increase bolt thrust, is more difficult to get to stay under the rails, and stretches brass.
There is neither timeliness nor elegance in these new cartridges.
I agree that they are just a marketing gimmick.
A 400 H&H Improved might be just the ticket though - but a 416, either Rigby or Remington, seems more sensible.
The .400 H&H could shoot .41 pistol bullets as practice loads, which some on this list think is a Good Thing in and of itself.
I am thinking about converting one of my .375 H&Hs to .400 H&H, especially after reading the information I have in various books covering the .500/.450 and .400 Pondoro.
