The .242 Rimless Nitro Express, also known as the .242 Vickers and initially called the .242 Manton, was a rimless bottleneck centerfire rifle cartridge developed by Kynoch for J. Manton & Co of Calcutta and introduced in 1923. [1] [2]

The .242 Rimless is very similar to the .243 Winchester in performance, although the cartridge is significantly longer. It fired a 100 gr projectile at 2800 fps. [1] [2]

<span class="mw-page-title-main">Express (weaponry)</span> Term applicable to hunting rifles and ammunition

The term express was first applied to hunting rifles and ammunition beginning in the mid-19th century, to indicate a rifle or ammunition capable of higher than typical velocities. The early express cartridges used a heavy charge of black powder to propel a lightweight, often hollow point bullet, at high velocities to maximize point blank range. Later the express cartridges were loaded with nitrocellulose-based gunpowder, leading to the Nitro Express cartridges, the first of which was the .450 Nitro Express.

The Nitro Express (NE) series of cartridges are used in large-bore hunting rifles, also known as elephant guns or express rifles, but later came to include smaller bore high velocity British cartridges.

The .600 Nitro Express is a large bore Nitro Express rifle cartridge developed by W.J. Jeffery & Co for the purpose of hunting large game such as elephant.

The .577 Nitro Express is a large-bore centerfire rifle cartridge designed for the purpose of hunting large game such as elephant. This cartridge is used almost exclusively in single-shot and double express rifles for hunting in the Tropics or hot climates in general and is a cartridge associated with the golden age of African safaris and Indian shikars.

<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.

.450 Nitro Express also known as the .450 Nitro Express 314-inch is a rifle cartridge designed for hunting dangerous game such as elephant, rhino, cape buffalo, lion, and leopard. This cartridge is used almost exclusively in double rifles for hunting in the Tropics or hot climates in general and is associated with the Golden Age of African safaris and Indian shikars.

The .280 Ross, also known as the .280 Nitro, .280 Rimless Nitro Express Ross (CIP) and .280 Rimless cartridge, is an approximately 7mm bullet diameter rifle round developed in Canada by F.W.

The .505 Gibbs cartridge was designed by George Gibbs in 1911. The cartridge was originally known as the .505 Rimless Nitro Express. The C.I.P. refers to the cartridge as the 505 Mag. Gibbs in their publications. It is a .50 caliber (12.8 mm) rimless bottlenecked cartridge intended for magazine-fed rifles.

<span class="mw-page-title-main">.404 Jeffery</span>

The .404 Jeffery is a rifle cartridge designed for hunting large, dangerous game animals, such as the "Big Five" of Africa. The cartridge is standardized by the C.I.P. and is also known as .404 Rimless Nitro Express. 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. 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 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.
