7x57 unmarked dummy

Found at today’s excellent British ECRA meeting at Bisley, this unmarked 7x57 dummy cartridge.

There’s no headstamp on the brass case, the brass primer is struck, it’s got 5 flutes and the hollow bullet part is pinned into the neck of the case … altogether a very nice dummy/exercise cartridge.

I’m told it was made in the US but does anyone know when, by which factory and for whom was it done ?


Peter, I may need glasses but why does this one look like a 7.62x63 (30-06)?

EDIT: naughty you! Now the image fits. :)

Simple Alex, as I was writing my second post it struck me that I’d mixed the picture captions up … whoops !

Oh, that happend to me before…
