Another old casing I can't ID:

I found another old casing that I need help with identification:

No Head Stamp.
Rimmed Centerfire Rifle
Length of Case: 2.010"
Head Diameter: 0.572"
Rim Diameter: 0.673"
Diameter at Shoulder: 0.555"
Neck Diameter: 0.514"
Inside Neck Diameter: 0.500" (or 0.474" as neck is a bit out of round)

I found this casing laying along the old Oregon Trail in centeral Wyoming it is in pretty good shape, but the neck is a bit bent so the measurements here are a bit subjective.

If anyone has a collection they could measure and shed some light on this round, It would be greatly appriciated. Thanks in advance.

I'm looking down thru the specs page of obsolete US cartridges in 11th Ed of Barnes Cartridges of the World , but your measurements don't jibe with anything.

Does the case appear to be a straight-walled or slight bottleneck?


Bingo!

listed under military cartridges is the 11.4x50Rmm Brazillian Comblain M74(?). Chambered in Remington Rolling Blocks sold to Brazillian Civil Guardia.


Base dia. .588''
Rim dia .682''
Case length 2.02''
Neck dia .494''
Shoulder dia .530''

I'll bet thats it! It does have a slight bottle neck. I will take a picture when I get the time and post it here!

This is the second case ID'ed here on TFL! The first was a Spencer Rimfire I found this summer.

Lots of cool stuff out there. Thanks again.

mkk41, does the book say anything about the year the guns were made. Maybe in the early 1880's? Thanks.

Doesn't really say , other than it is rarely seen in the US. I suspect the M74 stands for Model of 1874 , which was the heyday of the Rolling Block.
