>>The Cowboy .45 Special is a
case that is optimised for use
with light loads in .45 Colt
calibre revolvers for Cowboy A
ction Shooting. Light loads wi
th excessive airspace are a re
cipe for case splits and errat
ic function. By using the Cowb
oy .45 Special case, with its
.45 Colt rim and .45 Auto leng
th, the problem no longer exis
ts. While many claim that .45
Auto load data can be used in
this calibre, it is important
to realize the limitations of
the firearm it is chambered in
and only use loads that fall
within the pressure range of t
hat firearm. Generally these c
an be loaded using .45 Colt di
es and a modified (shortened)
crimp die, or .45 Auto Rim rol
l crimp die.
