DesignThe .300 Sherwood is a straight, rimmed cartridge that fires a {{convert|140|gr|g|abbr=on}} bullet, driven by {{convert|8.5|gr|g|abbr=on}} of cordite, at a listed speed of {{convert|1400|ft/s|m/s|abbr=on}}. The bullet calibre is {{convert|.300|in|mm|abbr=on}} as opposed to the more common {{convert|.308|in|mm|abbr=on}}. The cartridge was available in both solid lead and the then revolutionary LT-capped{{refn|group=note|The LT-capped bullet was named after Leslie B Taylor (1863-1930) an engineer and lifelong employee at Westley Richards who, among many inventions, designs and patents, invented the ‘Capped Bullet’, a revolutionary bullet design that allowed for both maximum shock effect whilst ensuring maximum stability and accuracy.[2]}} bullets were available.[1] HistoryThe .300 Sherwood was introduced by Westley Richards in 1901 in response to W.W. Greener's .310 Cadet cartridge.[1] The cartridge was created by lengthening the much milder .300 Rook.[5] As expected, the first rifles chambered for it were made by Westley Richards both in a miniature Martini actioned single-shot rifle and the "Sherwood" target rifle,[6] a modified takedown Martini actioned rifle with an easily removable barrel and a detachable lock mechanism held in place by a thumb screw.[5] Later other manufacturers produced rifles in the caliber including BSA, Vickers and Francotte, whilst high end double rifles were produced by Holland & Holland and Westley Richards. As recently as 2002, Westley Richards produced a double rifle in the .300 Sherwood.[6] The .300 Sherwood was a notably accurate target round, but arrived at the point when miniature rifle shooting was moving towards the .22 Long Rifle, shorter ranges and more indoor competition.[9] UseWhilst a noted target round, the .300 Sherwood was also used for hunting, it was considered more suited for small deer than for small game.[9] Henry Sharp, in his 1906 book Modern Sporting Gunnery, quotes hunters in British Columbia who used the .300 Sherwood to kill bears, bighorn sheep, and one verified caribou at {{convert|220|yd|m|abbr=on}}.[5] Notes1. ^1 2 3 Frank C.
