The .475 Wildey Magnum is a large semiautomatic pistol cartridge designed for big game hunting in the Wildey pistol.
History
The .475 Wildey Magnum was designed to be a hunting round. Cases are formed from .284 Winchester brass with the neck cut down and widened to take a .475-inch bullet, and the length is the same as the .45 Winchester Magnum. Velocity at 100 yards is equivalent to the muzzle velocity of the .44 Magnum.[2][3][4]
In the late 1980s, Wildey, Inc. produced three additional calibers using necked-down versions of the .475 Wildey Magnum brass casing originally designed in 1983 to achieve higher velocities and muzzle energies.[5] First was the .357 Wildey Magnum (also known as the .357 Peterbuilt) which used a .357 Magnum bullet. Second was the .41 Wildey Magnum (also known as the 10mm Wildey Magnum) which used a .41 Magnum bullet. Last was the .44 Wildey Magnum (also known as the 11mm Wildey Magnum) which used a .44 Magnum bullet.[6] All calibers were eventually discontinued.
The .45 Wildey Magnum was introduced by Wildey F.A., Inc. in 1997, which is also a necked-down version of the .475 Wildey Magnum using a .45 ACP bullet. It was discontinued in 2011 when overall production ceased.[7]
