Reference: Barnes, F C : 1972 : Cartridges of the World : Digest Books Inc : : p 213. Description: designed by F.W. Jones, a consultant for Eley, on behalf of the colourful rifle maker Sir Charles Ross, this was introduced in his Canadian-made straight-pull bolt action rifle in 1906. Despite its name, it actually uses a semi-rimmed bottlenecked case. It was one of the first successful modern high velocity small bore cartridges, and enjoyed a considerable if brief vogue as a hunting round in the years before the First World War. It appears that Ross considered the round to have military potential, and it was certainly used for long range Match Rifle shooting, an area in which Kings Norton was also active. It initially gained its reputation as a hunting round because of its evident 'knock-down' effect on thin skinned game, but this began to sour when it was used on more dangerous game, which, if not killed outright, on occasion turned on the hunter with fatal results. Within its limitations, it was a very good cartridge.
