Wolfe Publishing Co.:Prescott, Arizona. pg. 235 1-879356-00-7 The cartridge is standardized by the C.I.P. and is also known as .404 Rimless Nitro Express (Riml.

Jeffery & Co. to duplicate the performance of the .450/400 Nitro Express 3-inch in bolt-action rifles.Howell Ken Designing and Forming Custom Cartridges 1995 Precision Shooting 330, 331 0-9643623-0-9 The .404 Jeffery fires a bullet .422 in mm in diameter of either 300 gr with a muzzle velocity of 2600 ft/s m/s and muzzle energy of 4500 ft.lbf N.m or 400 gr on with a muzzle velocity of 2150 ft/s m/s on and 4100 ft.lbf N.m on 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 mm on bullets of 400 gr on at 2400 ft/s m/s on with a muzzle energy of approximately 5000 ft.lbf N.m on. 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.Geer Galen L. The .404 Jeffery https://africanxmag.com/2024/06/08/the-404-jeffrey/ 2 March 2026 African Expedition Magazine Guns 8 June 2024 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.“PROVED ON SAFARI” 1964 WINCHESTER FIREARMS PROMO FILM https://www.youtube.com/watch?v=YczDKqKlQ78 PeriscopeFilm - YouTube © Winchester 2 March 2026 Video 1964 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. A more recent development by Norma of Sweden has been the introduction of 400 gr on & 450 gr on ammunition under their African PH banner.African PH https://www.norma-ammunition.com/products/hunting/norma-african-ph Norma Ammunition Norma Precision 2 March 2026 The increase in bullet weight and sectional density improves the ballistics of the .404 Jeffery. With velocities of 2325 ft/s m/s on & muzzle energy of 4802 ft.lbf J on (400 gr) and 2150 ft/s m/s on & 4620 ft.lbf J on (450 gr), the cartridge is almost as powerful as the .416 Rigby, with a relatively mild recoil due to the efficient design of the cartridge.Norma Solid .404 Jeffery (Riml.

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.Hutchinson Gordon The short, fat paradox https://www.louisianasportsman.com/general/the-short-fat-paradox/ 2 March 2026 Louisiana Sportsman © Louisiana Sportsman, Inc. 29 December 2012 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 derived from the .404 Jeffery case.Massaro Philip Behind the Bullet: .300 Winchester Short Magnum https://www.americanhunter.org/content/behind-the-bullet-300-winchester-short-magnum/ 2 March 2026 American Hunter Guns, Gear & Ammo National Rifle Association of America 3 November 2020 Both the Winchester and Remington cartridges have also spawned many current wildcats, like the popular .338 Edge.Carlock Shawn .338 Edge https://defensiveedge.net/338-edge/ 2 March 2026 Defensive Edge 5 March 2020 Rathdrum, Idaho 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, are based on .404 Jeffery.Cooper Jeff Kirchner Paul To Ride, Shoot Straight, and Speak the Truth 1998 Paladin Printing 9780873649735 https://www.abebooks.com/servlet/SearchResults?ds=20&kn=0-87364-973-7&ref_=ds_ac_d_13&sts=t English Soft Cover More examples of the popularity of creating small-bore, high-velocity cartridges based on the .404 Jeffery design are the .26 Nosler,Massaro Philip Behind the Bullet: 26 Nosler https://www.americanhunter.org/content/behind-the-bullet-26-nosler/ 2 March 2026 American Hunter Guns, Gear & Ammo National Rifle Association of America 1 September 2023 .28 Nosler, .30 Nosler, and the .33 Nosler, introduced by Nosler between 2013 and 2016.33 NOSLER RIFLE CARTRIDGE https://www.nosler.com/explore/nosler-cartridges/33-nosler-rifle-cartridges Nosler.com Nosler Inc. 2 March 2026 See also 10 mm caliber List of rifle cartridges Table of handgun and rifle cartridges References Barnes Frank C.
