context_page_description: The 8 bore, also known as the 8 gauge, is an obsolete caliber used commonly in the 19th-century black-powder firearms.
context_section_description: When the Dutch established the Dutch Cape Colony in the 17th century, they soon discovered their muskets were hopelessly inadequate against local game. Within a century the most popular Boer firearm was a flintlock smoothbore musket of about 8 bore with a 5–6 foot long barrel. Early British settlers of the Cape Colony in the 18th century also found specialist firearms were required for the local game. British and European gunmakers responded with various long arms from the enormous (although seldom produced) 2 bore down.
  By the 19th century, the giant 4 bore had been established as the standard elephant gun amongst European settlers and explorers within Africa, whilst the 8 bore was considered the standard for all other dangerous game. Typical 8 bores weighed 15 to 16 lb (6.8 to 7.3 kg), and fired a 1,250 gr (81 g) conical bullet at around 1,500 ft/s (460 m/s) or an 860 gr (56 g) spherical ball at around 1,650 ft/s (500 m/s), both with 10 to 12 drams (17.72 to 21.26 g) of black powder, although sometimes heavier charges of 14 drams (24.82 g) were used, generally in Africa.
  In the late 19th century William W Greener conducted the most thorough research of any gunmaker into the requirements for African hunting. After extensive testing and lengthy discussions with returned hunters and adventurers, including Sir Samuel Baker, he concluded the 8 bore was the largest practical calibre required for hunting dangerous game. Additionally, due to the increased felt recoil of rifled weapons, he recommended the 8 bore as the largest calibre for a rifle, and that firearms above 8 bore be smoothbores.
  The most common 8 bore cartridges used paper cases, much like shotgun shells, and true .835 in (21.2 mm) caliber projectiles. A larger version utilising a thin brass case was also available, although it fired .875 in (22.2 mm) projectiles, in reality making it a 7 bore.
