The .475 Linebaugh is a high-powered revolver cartridge developed by John Linebaugh in the late 1980s. It was specifically designed for big-game hunting, particularly suitable for tackling large and dangerous game due to its high stopping power. The cartridge is based on a lengthened .45 Colt case, expanded to accept .475-inch diameter bullets, allowing for significant velocity and energy. Typical bullet weights range from 325 to 420 grains, with velocities from 1,200 to 1,400 feet per second.
In terms of performance, the .475 Linebaugh offers deep penetration and exceptional knockdown power, making it a favorite among handgun hunters in North America and Africa for game like bison, moose, and even elephants. Revolvers chambered for this cartridge, such as those made by Freedom Arms, tend to be robustly built to handle the high pressures generated by firing this powerful round.
