>>The .455 Webley MKII is a
British revolver cartridge
designed for their military in
the late 1800's. This brass
will work for all Webley MKII,
MKIII, MKIV, MKV and MKVI
cartridges.
The original MKI case is
longer, but this will work as
a short substitute for it. It
is important to note that the
Webley cartridges designations
don't necessarily coincide
with that
model revolver, and smokless
powder loads may not be safe
in all revolvers.
>>It is important to note that
many Webley revolvers in the
US have been modified to use
the much thicker rimmed .45
Auto Rim cartridge by
machining the cylinder
to accept the thicker rims.
Firearms modified as such will
not work with standard .455
MKII brass.
