.280 Ross
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.〔
== History ==
The .280 Ross was the first practical cartridge to reach the edge of 3,000 ft/s (910 m/s). Sir Charles Ross did many attempts while in the process of creating the "perfect cartridge", one of them leading to the creation of the .28-1906 in November 1906.
Ross also tried to convince the British War Department to adopt the .280 Ross (and his rifle) as the new service cartridge, but World War I came along and dashed his hopes.
The .280 also paved the way for Sir Charles' newly designed bullets such "Full Metal Patch" and "Metal Covered Hollow Point". The Ross Mk III rifle was especially developed to handle the .280. The .280 (and the Ross Rifle) won the famous Bisley international matches in 1908, 1912 and 1913 (King's Prize) plus many other prizes in different competitions on both sides of the Atlantic.
