Biography
John Linebaugh was born on November 15, 1955, in Pickering, Missouri.[2] Linebaugh's early efforts started in the 1970s, where he produced revolvers made to handle much more powerful loadings in .44 Magnum and .45 Colt, and then later on expanded into creating his own cartridge designs.[3] After inventing the .500 Linebaugh and .475 Linebaugh cartridges, he later created a variant of each cartridge, lengthened to 1.61 inches, and appended "Maximum" to their names.[4] Linebaugh focused on developing cartridges which were compatible with standard-size revolvers, keeping them "old school" or "packable" rather than oversize.[3]
Linebaugh died in Clark, Wyoming, on March 19, 2023, at the age of 67.[5] He was laid to rest on March 28, 2023, at the Bennett Butte Cemetery[5] in section 108–5.[6]
