Just saw this interesting article on The Firearm Blog about the .5 Vickers, a 600 Nitro Express case necked down to 50 cal. It faded away because it was less powerful than the 50 BMG, but I'm guessing it might have potential as a sporting round these days?

Thanks for posting.
That is an interesting find. I never knew that existed. If the poms had of been using that instead of their 303 in their fighters the Germans would of lost more aircraft in the Battle of Brittan. Also in the turrets of their bombers.
I know they should of gone to the 50BMG far earlier but was just thinking the .5 Vickers would of produced less recoil so could of been used without increasing the weight as much esp. in the bomber turrets. Any how that is just speculation.

G'Day Fella's,
Just when you think you have heard of or read about most things, the .5 Vickers comes along!
Thanks for sharing Mehul.

Either the rimless or semi rimmed case look quite good. Tapered case or easy feed and extraction.
Might be a little high pressured for the tropics, but there are certainly worse options out there.
As a parent case for "new" cartridges........

EE, where abouts did you find the information on what pressure it ran? I couldn't find it, but I'm interested at what it would be all the same. Surely it would be less than the 50 BMG, and that worked fine in the tropics. As a sporting round at 2650 fps? Ouch comes to mind in anything light enough to carry in the bush. Be effective though

Just finished reading the link to the Vickers site, thank you so much for putting it up it was fascinating.

Well I guess we didn't see this one coming!
Bet one of our American friend across the pond use this one as a basis for a sniping round! 
Like comparing the .308 & 30/06 side by side, only its a .50Vickers & .50 Browning!
Outstanding find!

You think it a beast? I read about this one the other day. 14.5mm kicker!
Azeri Ministry of Defense showcased their new bolt action, magazine fed, 14.5mm NST rifle. It weighs 20 Kg, has an maximum range of 2000 meters, and a maximum effective range of 1600 meters. The scope and muzzle brake are both designed locally in Azerbaijan.

Gryphon,
I'm guessing that's based on the Degtyarev machine gun round. The .5 Vickers is interesting to me, because it was based on a sporting round. With monster sporting rounds like the 600 Overkill being greeted with glad cries by big bore aficionados these days, perhaps someone will revive this old warrior for sporting use these days . . .

G'day,
It's a SWAG based on performance, projectile weight and a guesstimating of case volume.
The aircraft weapons could often operate at higher pressures because their operating environment was at higher altitudes, so cooler ambient temperatures.
The tank rounds however, may have been a different spec.

interesting cartridge, think I notice this years ago as a possible sporting rifle cartridge dont knowing it is a 600/500 Nitro express rimless
here is more about it https://sites.google.com/site/britmilammo/-5-inch-vickers
"Evolution of the Vickers round from the rimmed, necked down .600 Nitro Express to the initial production .5 Vickers Ball round headstamped "R/|\L 22 469" "
"Eley Brothers were tasked with the design of the new round. They decided to begin by necking the .600 Nitro Express to .5 inch calibre, and initial trials were held with a rimmed case and round nosed bullets. The case was then redesigned with a belt and became the .600/.500 inch, first using the round nosed bullet and then a range of spitzer bullets. Ball, SPG tracer, armour-piercing, Buckingham and RTS/RTT explosive bullets were tested before the war ended. The new round was to be fired in scaled up Vickers and Lewis guns and also in an anti-tank rifle designed by Mr.Godsal at Webley & Scott. (See here)
The rounds were headstamped "ELEY .600/500" and when the case was strengthened slightly and the fireholes modified "ELEY .600/500A".
The Armour-Piercing round had a 570 grain bullet with a propellant charge of 135 grains od Dupont No.16 nitrocellulose to give a velocity of 2,650 feet per second.
Work continued slowly post war, the case was modified again and the belt omitted. By 1922 the case design had been finalised and with a bullet to Design RD 469 this was approved as the .5 inch Ball Mark I."
as a bycatch something about nitro express rifles in the great war https://sites.google.com/site/britmilammo/express-rifles

Sounds just a bit less powerful than some of Ed Huble's rounds.
