The .475 Wildey Magnum is a large semiautomatic pistol cartridge designed for big game hunting in the Wildey pistol.

The .475 Wildey Magnum was designed to be a hunting round.

[2][3][4] While not being very common, the .475 Wildey Magnum is most famous for its appearance in Death Wish 3, where the Wildey (chambered for this cartridge) was a signature weapon of Paul Kersey, a character portrayed by Charles Bronson (using his own personal Wildey firearm) in the Death Wish film series.

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.
