455 Webley MKII (Large Pistol primer)

The .455 Webley MKII is a British revolver cartridge designed for their military in the late 1800's. 

This brass will work for all of the 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.
