I know the rim diameter is .805" however, I need some other dimensions from those who have some cases please.

Rim= .805"
Rim thickness= ??
Case diameter near rim= ??
Case diameter near middle= ??
Case diameter near mouth= ??
Case length= ??

Also if you could state the Mfgr of the brass (Bertram, bell, RMC, Searcy, etc) that would be great.
Thanks in advance.

BMG- It's in the A-square book! I think thecase length is 2.990-Rob

These are data from Cartridges of the World, 9th (most recent) Edition:

.600 Nitro Express

Bullet Dia.--0.620"
Neck Dia.--0.648"
Base Dia.--0.697"
Rim Dia.--0.805"
Case Length--3.00"
Cartridge Length--3.68"
Berdan Primer Size--0.254"

Hope this helps.

The .600 NE has the standard British thick rim, being developed as a nitro cartridge without any BP ancestry. Bill Fleming measured stacks of Kynoch factory loads, rim thickness min. 60 thou, max. 65 thou.
