.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 Magnum
chambering 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 ACP case
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 ACP
case.
Any bullets of nominal .451 to.452 inch diameter presently made for the
.45 ACP and
.45 Colt are
suitable for the .45 Winchester Magnum handloads. Excellent bullets for use
on deer size game are the Sierra
240 grain, Hornady 250 grain, and the
Speer 260 grain jacketed hollow points. For maximum velocity, H110 is the
powder to use, but it does not burn quite as cleanly in the .45 Magnum as
HS-6 and
HS-7.
