.45 Winchester Magnum

If the truth be known, the .45 Winchester Magnum was probably spooked from the bushes by the introduction of the .44 Auto Mag. Introduced in 1979, the .45 Winchester Magnum is an excellent cartridge, but it was doomed form the start by the on again, off again availability of the Wildey autoloader. Now that the .44 Magnumchambering is available in autoloading handguns, it is doubtful that the .45 Magnum will ever become a raging success. The .45 Winchester Magnum case is a stretched version of the .45 ACPcase with the rear section of its wall made considerably thicker. When used in an autoloader that does not fully support the rear of the case wall, this important difference in design enables the .45 Magnum case to safely contain chamber pressures far higher than possible with the weaker .45 ACPcase.
