Sixguns
Elmer Keith (1899-1984) was a rancher and firearms author who helped to develop the .357 Magnum, .41 Magnum, and .44 Magnum.  Keith, an expert cartridge reloader, also developed his own style of semi-wadcutter bullet, called the Keith style bullet. Keith served as a key link between the gunmen of the late 1800's and modern firearm enthusiasts.  His interactions with Civil War veterans and western gunfighters gave Keith unique knowledge which he carried well into the 20th century.
