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. Jones as a consultant to Sir Charles Ross, 9th Baronet, and his Ross Rifle Company of Quebec, Canada for use as a Canadian military cartridge as a replacement for the .303 British, and in a civilianised and sporterised version of his controversial Mark II and Mk III Ross rifle, and first commercially produced by Eley Brothers of London, England, in late 1907.
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.
