I found this case recently while poking around the remains of a homestrad in the Missouri River Breaks of central Montana. As you can see the headstamp is "30 USA-UMC-REM"


The dimensions are similar to the 30-40 Krag



Cartridges of the World state that the 30 USA is a "rimless version (of the 30-40) loaded by UMC (and) was offered for use in the Blake rifle". The (rimmed) 30 U. S. Army was apparently issued in 1892 but I'm not sure if this is the same cartridge. Does anyone know more about the rimmed 30 USA and when it was issued (looks to be solely a military cartridge)? You spend time in that country, especially in the breaks near the river and you can begin to see 1892--I'm really interested in the history of the cartridge--seems like a story's in here somewhere.

It is the .30-40 krag an early headstamp though.
they were also marked .30 U.S.G..
My book also state the same in a rimless version could be a typo or just elusive.

Snowcat,

Give this link a try: http://www.cabincreekcds.com/BlakeRifle1897.htm

The .30/40 Krag (rimmed!!) was also known as the .30 U.S. Army (.30 USA) and as the .30 U.S. Government as well as .30/40 Krag.... I'm sure this got somewhat confusing after the advent of the .30/'06, as I have seen Peters .30/'06 cases that were stamped .30 U.S. Gov't also!!

Coincidence...last week hiking in the Califorinia mountains I found a severly corroded 30-40 case stamped exactly the same!
