You see .. you can learn something new every day 🙂
- Look .. You don't know what you don't know eh.
For starters - I read that the Webley-Green revolvers are more properly called the 'Webley Government' Model - but I don't get too excited about that sort of thing .. you can call me Marty or Martin - or even "Kav" and I won't object ... Although I did once work with a freak called Tony who insisted that his name was 'An-Thony' as per it's spelling ... so I thereafter made a point to call him "Thony" at every chance.
Well good old Wikipedia came to the caliber-party and explained that the .455" round used a .455" (or .454") diameter bullet - as did the earlier .476 round - which was named after it's .476" diameter case.
It seems that.450 Adams, .476 Enfield (Eley), and .455 Webley cartridges could all be fired in the Webley Government model revolvers - as they all used .450+" - .455" bullets from a similar case.
Confused again by calibers?.. I think that the bore size is or was .450 +". Please note that both bore and cylinder throat sizes are found to be variable - but the generally soft lead projectiles give a degree of flexibility.
This model .455" caliber revolver was bought privately by many British officers and NCOs - and used in the Boer War - plus both WWI & WW2 with whatever iteration of cartridges they might be issued with..
I get the idea that these 'different' cartridges were various "loadings" from the Black-Powder and 'Cordite', & smokeless-powder change over periods with slightly different case length, bullet weight and shapes, and various powder charges for use in .450" bore revolvers from the 1880s.
Enfield Cartridges - They Look A Bit Ugly Eh.
- Google is your friend .. Or have a look at this tale about these old .455' & .450" cartridges. Link:
