The Magnum Research BFR is a single-action revolver manufactured by Magnum Research. Modeled after the Ruger Blackhawk, it is constructed of stainless steel and chambered for a number of powerful handgun cartridges, such as .460 S&W Magnum and .500 S&W Magnum; popular rifle chamberings, including .30-30 WCF, .444 Marlin, and .45-70 Government; and even .410 bore shotshells. Notably, the BFR platform has also served as the basis for custom caliber conversions to 19th century big game cartridges such as the .50-110 WCF and .50-90 Sharps, as well as the .500 Bushwhacker, which is currently considered to be the most powerful handgun cartridge in the world in terms of muzzle energy.[2] The name "BFR" originally stood for “Brainerd’s First Revolver”, in reference to Brainerd, Minnesota, where the early BFRs were manufactured.[3] Officially the acronym now stands for "Biggest, Finest Revolver",[4] though it was rebranded for a time as the “Big Frame Revolver” after Magnum Research’s 2010 acquisition by Kahr Arms.[5] It is sometimes referred to as the "Big Fucking Revolver", but this is a misnomer often used for humorous effect and has never been officially sanctioned by manufacturers.[6][7]
