The .404 Jeffery is a rifle cartridge designed for hunting large, dangerous game animals, such as the "Big Five" (elephant, rhino, cape buffalo, lion and leopard) of Africa. [5] The cartridge is standardized by the C.I.P. and is also known as .404 Rimless Nitro Express. [6] It was designed in 1905 by London based gunmaker W.J. Jeffery & Co to duplicate the performance of the .450/400 Nitro Express 3-inch in bolt-action rifles. [7] The .404 Jeffery fired a bullet of .422 in (10.72 mm) diameter of either 300 gr (19 g) with a muzzle velocity of 2,600 ft/s (790 m/s) and muzzle energy of 4,500 foot-pounds force (6,100 N⋅m) or 400 gr (26 g) with a muzzle velocity of 2,150 ft/s (660 m/s) and 4,100 foot-pounds force (5,600 N⋅m) of energy. It is very effective on large game and is favored by many hunters of dangerous game. The .404 Jeffery was popular with hunters and game wardens in Africa because of its good performance with manageable recoil. By way of comparison, the .416 Rigby and .416 Remington Magnum cartridges fire .416 in (10.57 mm) bullets of 400 gr (26 g) at 2,400 feet per second (730 m/s) with a muzzle energy of approximately 5,000 foot-pounds force (6,800 N⋅m). These cartridges exceed the ballistic performance of the .404 Jeffery but at the price of greater recoil and, in the case of the .416 Rigby, rifles that are more expensive.

History

Originally the .404 Jeffery was very popular with hunters in Africa and saw significant use in both British and German colonies. As the British Empire began to shrink, many of the popular British big-bore cartridges also dwindled in popularity, and the .404 Jeffery was one of them. By the 1960s it had all but disappeared from common firearm usage. This condition was mostly the result of the closing of the British ammunition giant Kynoch, which was the primary manufacturer of the .404 Jeffery and many other British cartridges. The introduction of the .458 Winchester Magnum in 1956 in the Winchester Model 70 bolt-action rifle provided an affordable alternative to the big Nitro Express rifles and cartridges. Winchester also started a marketing campaign at about this time called "Winchester in Africa" with much success. Renewed interest in heavy game rifles combined with political stability in Africa has led to a resurgence in African hunting and the rifles suited for it. Several ammunition makers like Kynoch, Norma, Federal, and Hornady are offering .404 Jeffery sporting ammunition.[ citation needed ]

A more recent development by Norma of Sweden has been the introduction of 450 gr ammunition under their African PH banner. The increase in bullet weight and sectional density improves the ballistics of the .404 Jeffery. Fired at 2,150 fps, the cartridge now outperforms most of its peers with a relatively mild recoil due to the efficient design of the cartridge.[ citation needed ]

Commercial variations

In 1908, W.J. Jeffery & Co created the .333 Jeffery by shortening the .404 case, giving it greater taper and necking it down to .333 in (8.5 mm). [8] In 1913, Jeffery further necked down the .333 Jeffery to .288 inches, creating the .280 Jeffery.

In recent times, the .404 case has seen a resurgence in use by wildcatters. This case has no belt, unlike many other magnum cartridges, which can be desirable for handloading because of possible problems with case head separation with repeated reloading of belted magnum cartridges. The rimless design also contributes to smooth feeding from the box magazine of bolt-action rifles.

Some common commercial children of the .404 Jeffery case are the Remington Ultra Magnum (RUM) cartridge family, which in turn spawned the Remington Short Action Ultra Magnum (RSAUM) cartridges. Also, the Winchester Short Magnum (WSM) and the Winchester Super Short Magnum (WSSM) families are believed to derive from the 404 Jeffery case. Both the Winchester and Remington cartridges have also spawned many current wildcats, like the popular .338 Edge.

All but one (.450 Dakota, based on .416 Rigby) of the proprietary cartridges of Dakota Arms such as .375 Dakota, and the .400 Tembo by Velocity USA, and the once-famous .460 G&A, used by Jeff Cooper in his "baby" rifles, [9] are all based on .404 Jeffery.

More examples of the popularity of creating small-bore, high-velocity cartridges based on the .404 Jeffery design are the .26 Nosler, .28 Nosler, .30 Nosler and, the latest, .33 Nosler, introduced by Nosler between 2013 and 2016.

<span class="mw-page-title-main">9.3×62mm</span> Rifle cartridge

The 9.3×62mm is a rimless, bottlenecked rifle cartridge designed in 1905 by German gunmaker Otto Bock. It is suitable for hunting medium to large game animals in Africa, Asia, Europe, and North America. At a typical velocity of 720 m/s (2362 ft/s), its 286 gr standard load balances recoil and power for effective use at 250m to 300m. The C.I.P. Maximum Average Pressure (MAP) for the 9.3×62mm is 390.00 MPa (56,565 psi).

<span class="mw-page-title-main">.458 Winchester Magnum</span> Rifle cartridge

The .458 Winchester Magnum is a belted, straight-taper cased, Big Five game rifle cartridge. It was introduced commercially in 1956 by Winchester and first chambered in the Winchester Model 70 African rifle. It was designed to compete against the .450 Nitro Express and the .470 Nitro Express cartridges used in big bore British double rifles. The .458 Winchester Magnum remains one of the most popular large game cartridges, and most major ammunition manufacturers offer a selection of .458 ammunition.

The .416 Rigby is a rifle cartridge designed in 1911 by London based gunmaker John Rigby & Company, for hunting dangerous game. It is the first cartridge to use a bullet of .416 inch diameter. The rifles, as built by John Rigby & Co., were initially made up on the Magnum Mauser 98 action, although in later years, some were made on standard length actions, a perfect example being the rifle used by legendary professional hunter Harry Selby. Other famous users of the cartridge were Commander David Enderby Blunt, John Taylor, and Jack O'Connor.

The .257 Weatherby Magnum is a .257 caliber (6.53 mm) belted bottlenecked cartridge. It is one of the original standard length magnums developed by shortening the .375 H&H Magnum case to approx. 2.5 in (64 mm). Of the cartridges developed by Roy Weatherby, the .257 Weatherby Magnum was known to have been his favorite, and the cartridge currently ranks third in Weatherby cartridge sales, after the .30-378 Weatherby Magnum and the .300 Weatherby Magnum.

<span class="mw-page-title-main">.375 H&H Magnum</span> British rifle cartridge

The .375 H&H Magnum, also known as .375 Holland & Holland Magnum, is a medium-bore rifle cartridge introduced in 1912 by London based gunmaker Holland & Holland. The .375 H&H cartridge featured a belt to ensure the correct headspace, which otherwise might be unreliable, given the narrow shoulder of the cartridge case. The cartridge was designed to use cordite which was made in long strands – hence the tapered shape of the case, which, as a beneficial side effect also helped in smooth chambering and extraction from a rifle's breech.

<span class="mw-page-title-main">.300 Winchester Magnum</span> Rifle cartridge

The .300 Winchester Magnum is a belted, bottlenecked magnum rifle cartridge that was introduced by the Winchester Repeating Arms Company in 1963. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet.

<span class="mw-page-title-main">.338 Winchester Magnum</span> Rifle cartridge

The .338 Winchester Magnum is a .338 in (8.6 mm) caliber, belted, rimless, bottlenecked cartridge introduced in 1958 by Winchester Repeating Arms. It is based on the blown-out, shortened .375 H&H Magnum. The .338 in (8.6 mm) is the caliber at which medium-bore cartridges are considered to begin. The .338 Winchester Magnum is the first choice among professional brown bear guides in Alaska to back up clients where a powerful stopping caliber is required on charging bears. It is also the most popular medium-bore cartridge in North America and has the most widely available choice in rifles among medium bore rifles. The action length is the same as a .30-06, and most major rifle manufacturers in the United States chamber rifles for the cartridge including the semi-automatic Browning BAR Mk II Safari, making it a very powerful combination against charging dangerous game. The cartridge was intended for larger North American big-game species and has found use as for the hunting of thin-skinned African plains-game species.

<span class="mw-page-title-main">9.5×57mm Mannlicher–Schönauer</span>

The 9.5×57mm Mannlicher–Schönauer (MS) cartridge was adopted for the M-1910 MS rifle and carbine in 1910. The 9.5×57mm MS is also known as the 9.5×56mm MS, the 9.5×56.7mm MS, and the .375 Rimless Nitro Express (RNE) × 2¼. The cartridge may have been created by Westley-Richards and Eley in 1908, but no production rifles in this caliber have been found prior to the M-1910. This development by or on behalf of Steyr was probably an answer to the development by the noted British gunmaking firm of Holland & Holland in 1905 of their .400/375 Belted Nitro Express, designed for their specially modified Mannlicher–Schoenauer rifle. Whether the development of the 9.5×57mm Mannlicher–Schoenauer cartridge originated with OWS or with Holland's British competitor, Westley Richards certainly was the principal promoter of the new 1910 Model Mannlicher–Schoenauer rifle as evidenced by catalogs of the time. The 9.5×57mm MS is the last pre-war proprietary cartridge by Steyr and their most powerful until the recent advent of the .376 Steyr, which has its antecedents in the 9.5×57mm.

The .416 Weatherby Magnum is a belted, bottlenecked cartridge designed by Ed Weatherby and launched commercially in 1989. It is a dangerous-game cartridge intended for the hunting of heavy dangerous game such as elephant and African Cape buffalo. It is considered the most powerful commercial .416 cartridge, besting the Remington, Rigby and Ruger .416s by a velocity of 300 ft/s (91 m/s). Unlike earlier Weatherby cartridges which were designed by Roy Weatherby, this cartridge was designed by his son Ed Weatherby.

<span class="mw-page-title-main">.416 Remington Magnum</span> Rifle cartridge

The .416 Remington Magnum is a .416 caliber (10.57 mm) cartridge of belted bottlenecked design. The cartridge was intended as a dangerous game hunting cartridge and released to the public in 1989. The cartridge uses the case of the 8 mm Remington Magnum as a parent cartridge. When the cartridge was released in 1988, author Frank C. Barnes considered the .416 Remington Magnum to be the "most outstanding factory cartridge introduced in decades".

The .375 Ruger (9.5×65.5mm) is a rimless, standard-length rifle cartridge designed for the hunting of large, dangerous game. It is designed to provide an increase in performance over the .375 H&H cartridge, yet to be chambered in a standard-length action rifle. The cartridge was designed in partnership, by Hornady and Ruger. In 2007, it was released commercially and chambered in the Ruger Hawkeye African and the Ruger Hawkeye Alaskan rifles.

<span class="mw-page-title-main">.325 Winchester Short Magnum</span> Rifle cartridge

The .400 H&H Magnum also known as .400 Holland & Holland Magnum is a belted rimless bottlenecked cartridge introduced by Holland & Holland. The cartridge was released together with the .465 H&H Magnum in 2003. It is based on the .375 H&H Magnum case.

The .500 Jeffery is a big-game rifle cartridge that first appeared around 1920, and was originally introduced by the August Schuler Company, a German firm, under the European designation "12.7×70mm Schuler" or ".500 Schuler". When offered by the famed British outfitter W.J. Jeffery & Co, it was renamed the .500 Jeffery so as to be more palatable to British hunters and sportsmen following World War One.

The .450 Rigby is a rifle cartridge designed in 1994 by John Rigby & Co. for the hunting of large, thick-skinned dangerous game animals in Africa. The cartridge is based on the .416 Rigby necked up to accept a .458 in (11.6 mm) bullet and is intended for use in magazine rifles. The cartridge should not be confused with .450 Nitro Express which was introduced by Rigby in 1898, and is a rimmed cartridge intended for use in double rifles.

The .333 Jeffery and .333 Jeffery Flanged are medium-bore rifle cartridges developed by W.J. Jeffery & Co and introduced in 1908.

The .350 Rigby and .350 Rigby No 2 are proprietary medium bore rifle cartridges developed by John Rigby & Company.

Nosler produces six different hunting cartridges. The first to be introduced was .26 Nosler, followed by .28 Nosler, .30 Nosler, .33 Nosler, .22 Nosler, and .27 Nosler.
