Can anyone tell me the actual diameter of the original .475 NE. (the staright walled version cartridge, which I think was made for 75 grains of cordite with a 480gr bullet)

I am not refering to the No. 2 (which I know is .483 or .488 for the Jeffery verison)

Thanks
Cheers

Donnely shows it as .476 as does COTW.

Kayaker & Mike:

Donnelly and COTW both appear to be wrong. The .475 3 1/4" NE uses the same .483" 480 grain bullet as the .475 No. 2 Eley. Original factory drawing from 1/24/1907 shows a .483" bullet. Subsequent drawing from 2/14/1907 also shows .483". This has certainly been so with the guns that I've seen. However, the bores of the individual rifle should
always be slugged.

Thanks again .400 Nitro, this would also explain why Woodleigh only makes .483 and .488 in the .475 category (although they only mention the No. 2's)

I was wondering about that, as Woodleigh is obviously up on the classic bore sizes...but makes no special mention of the .475NE 3 1/4". It is obviously its own usique case size I assume or based on the .500 3 1/4" case, but I understand is straight walled?(not based on the orignal Rigby 3 1/4" case used in the .450 3 1/4").

I also read that the original .475NE 3 1/4" is quite rare. I did see one in a Sarasqueta years back in a gun shop in Boksburg (near JHB). I am inproving my knowledge of doubles slowly...I just need to get down to owning one at some point!

Thanks and cheers

No, the .475 3 1/4" is based on the .450 3 1/4". Same .545" base diameter and .042" rim, just a bit of taper blown out. Apparently, Eley Bros. designed it for Cogswell & Harrison.

The .475 straight is common in rifles from Cogswell & Harrison and R. B Rodda. Aside from those two makers, yes, they're quite rare.

COTW seems to be wrong about half the time.

The British Sporting Rifle Cartridge section of COTW has been replete with errors for many editions.

Dan,
Don't be such a "pessimest"...

Be an "optomist", they are right about half the time.

I just pulled a 480 grain soft from a 475 3 1/4" 1930's era Kynoch cartridge. It measures .4828 on my caliper. Hoyem lists a bullet diameter of .482 for this cartridge. In my experience Hoyem's "History and Development of Small Arms Ammunition" has the most accurate data.
