11mm mauser cartridge

**duchamp** · 08-25-2008, 02:53 PM

i have an 11mm mauser cartridge with copper colored case and tombak or similar bullet, the only headstamp marking is a kind of an 'x' with the arms divided from a center dot, almost like an abstracted crossed cannon. any idea what this is?

A picture of the headstamp and ctg would help a lot..BILL

Did you make a typo on the base dia.,did you mean .504 instead of .540? If so your cartridge could be either a 40-70 Win. or a 40-82 Win.

its .540, a real mystery. it was given to me by a very knowledgable old timer who collected arms and ammunition his whole life. he amassed an incredible collection but had no idea what this one was. i would think the headstamp marking would be a givaway....i decided it was just 11mm mauser because thats what it looks like, but apparently this is not so. the flat tipped bullet suggests a tubular magazine.
