The Magnum Research BFR (Big Frame Revolver) is a premium, hand-built single-action revolver designed by gunsmith Jim Tertin in 1999. Known for its immense power and precision, it is widely used by handgun hunters and available in both short-cylinder standard handgun rounds and extended-cylinder rifle cartridges.The BFR was originally based on a concept developed in the 1990s by D-Max. The acronym originally stood for "Brainerd’s First Revolver", as it was first conceptualized and produced in Brainerd, Minnesota.The first three models offered were chambered for the .45 C**t/.410 shotshell, .454 Casull, and notably, the massive .45-70 Government rifle cartridge.BFRs have also been the base for custom conversions to extreme big-game calibers, including the .500 Bushwhacker, widely considered one of the most powerful handgun cartridges in the world.
