30 cal Duplex elongated neck blank?

#1

I have blank cartridge that looks all the world like a .30 cal. long neck duplex case with a 5 petal mouth crimp. OAL 2.468 in. HS WCC 54. Brass case and primer. Red primer seal.
Can anyone help?

Without a Pix, this sounds like a 1950s .30 cal case used to make a 7,62 Nato Long Blank ( Movie or re-enactor).
Very common method, as the 63mm length of the 30/06 case will give about a 64-65mm length blank when reformed, the correct Length of an Extended ( False Projectile) 7,62 Nato Blank. The “crimped” end gives it away as “Aftermarket”. US 7,62 Blanks are wadded, Only in about 2005 did they use a 4- petal long crimp ( Like the rest of the world.)

Hi Doc
Haven’t worked out how to insert pics yet.
This round won’t chamber in my 308.
The neck is straight with no reduction for “projectile”.
Some early experimental US blanks used a petal crimp around this era but I’ve never heard of any blanks in the SALVO series.

Bowerbird,

For some pointers on posting pictures look here: Ammunition Art

Look forward to seeing a picture of the cartridge in your question.

Not an answer to identifying the blank shown here but there is some discussion on .30 Light Rifle blanks: .30 Light Rifle T116 gone bad
