It’s chambered in the 3” 450/400 not the pretender 458Windbag.

Apparently, Craig had some influence on Ruger and Hornady on which cartridge to chamber/produce and Ross thought it should have been the other.

Beautiful rifle, Huvius. Mind if I ask who did the work? Apologies if you are the custom builder and I'm just out of the loop.

Don’t know what the heck is going on with him now but it doesn’t seem like a good situation for him.

I think he got it very close to right-on for this cartridge. A minor semantic issue only is claimed by me.

*.450/400 Nitro Express 3" (Jeffery)*

Cartridge History
The history of the .450/400 Nitro Express 3" Jeffery starts with the .450/400 Magnum Nitro Express 3-1/4" first listed in Kynoch's 1884 catalogue. That cartridge was the standard .450 NE 3-1/4" necked down to .409" calibre,
(Not quite, they were both the old BP cartridges, not Nitro Express cartridges in 1884! Just a little snafu with the nomenclature, since smokeless powder, flake or Cordite, and NITRO EXPRESS loads had not yet arrived.
Pierre surely means that these two aboriginal BP, BPE, and NFBPE cases were simply identical in their case designs to the later NE cartridges, the .450/400 NE 3-1/4" and its forerunner, the .450 NE 3-1/4".)
but initially suffered from the fact that the original black powder case's walls were too thin to work reliably with the nitro loads that generated higher pressures.

Just as this very problem spawned Eley's .450 No.2 cartridge, it also spawned Jeffery's .450/400 Nitro Express 3". Designed with thicker case walls to handle the higher nitro pressures, its date of birth is often claimed as 1896, but the most respected authorities such as Hoyem and Barnes dispute that, while Datig offers no date or explanation. Although introduction actually took place in

1987

1897,

it is not impossible that work on the design started a year earlier.

Let's look into the events which led to its introduction. Rigby's .450 NE 3-1/4" was the first medium bore (old British classification) big game cartridge for use in double and Farquharson falling block rifles loaded with the then new British smokeless propellant Cordite. Cordite, unfortunately did not prove as perfect as had been hoped for by its developers. Early results were mixed because the steels of the day were hardly up to the new pressure levels generated. Many a bulged barrel and/or destroyed action resulted from excessive pressures. Due to these problems, black powder express rifles remained in use well into the 1900's. It was not until about 1897-1900 that the British achieved success with their early large bore nitro cartridges. The three most popular were Rigby's .450 NE 3-1/4", followed closely by Jeffery's .450/400 NE 3" and later the .500 NE 3". Jeffery's .600 Nitro Express also gained some following. When Jeffery designed his .450/400 NE 3", he based it on the 1/4" longer Rigby .450 Bore. Unlike the other two .450/400 cartridges which started off as black powder cartridges, the .400 S Jeffery as it is also known, was designed from the outset to work with nitro propellants.

The .450/400 NE 3" entry was made in the Jeffery ledger on the 8 November 1897 under the designation .400S for a rifle with serial number 5766. The letter 'S', inred ink, denoted its smokeless propellant. Like Jeffery was wont to do with cartridges, the .450/400 NE 3" was not kept as a proprietary cartridge, but released to the trade, which accounts for its widespread use and popularity.

The .450/400x3" struck a nice balance between bullet weight and the velocity considered suitable for a wide range of game and consequently went on to become a greatly admired African cartridge; not only because of availability, but because of its performance as well.

More from Crag Boddington in the A-Square BOOK, ANY SHOT YOU WANT p.502, agrees very well with van der Walt:

.450/.400 N.E. (3")

The two versions of the .450/.400, the 3-inch and the 3-1/4-inch, are not interchangeable, although in power they are indistinguishable. The .450/.400 N.E. (3"), also called the .400 Jeffery, was developed by Jeffery around 1896. It was probably the first large bore cartridge specifically designed for use with the higher pressures produced by smokeless powder. The 3-1/4-inch version was essentially a blackpowder case, and the weaker, thinner, rolled brass cases were reported to cause sticky extraction with cordite powder, especially in tropical climates. Stronger drawn cases quickly solved the problem, but by then the .450/.400 N.E. (3") was already a reality.

Jeffery indeed shortened the case on their version, but that's not the only change. The Jeffery version had a stronger, heavier case and a much thicker rim -- .060-inch vice .040. These changes make the two cartridges, although ballistically almost identical, absolutely non-interchangeable ...

... Collectively, the two versions of the .450/.400 were almost certainly the most common of all the "over-.40" Nitro Express cartridges, and the 3" version was probably more popular than the longer case.
**********************************************************************************************************************************************

Craig may have been a bit exuberant in his imaginings of the rolled case .450/.400 N.E. 3-1/4" deficiencies?

However, George A. Hoyem says of the .450/.400-3-1/4", on page 115 of THE HISTORY AND DEVELOPMENT OF SMALL ARMS AMMUNITION VOLUME III (BRITISH SPORTING CARTRIDGES):
*******************************************************************************************************************************************
This long cartridge is based on the .450-3-1/4" necked to the smaller caliber. It does not exist in the rolled case Boxer style, but evidently appeared during the 1880s. It is illustrated in the Kynoch 1884 catalog. The black powder charge was 110 grains, bullet 230 grains in express form with copper-tube hollow point, or 255-grain solid lead. In the nitro-for-black form, the charge was 40 grains of smokeless powder with a 270-grain metal-based bullet. This cartridge carried over into the nitro era Yes, AFTER THE .400 S. JEFFERY 3-Inch PIONEERED THE WAY, the 3-1/4-Inch BP brass was also strengthened, though it retained the thin rim in the 3-1/4"version!
and was available with 60 grains of smokeless and a 400-grain jacketed bullet of various constructions. It was widely used by various makers in all forms for the double rifle.
******************************************************************************************************************************************

I rest my case, the .400 S. Jeffery case, aka the 450/400 NE 3-Inch.
