What kind of ammo is this?

[rabbitdave]

Hi,

I found some ammo that was mixed in with some WWII ammo I picked up. I am not sure what it is or if it is worth anything. I have never seen anything like it. It has a headstamp of SMI 934 so I found out that is Italian. But there is nothing I can find with the 934 number on the headstamp. The come in 5 round clips and look like the 6.5 x 52 carcano ammo, but they are 75 mm long. So they are bigger. Any ideas? Here is some photos.

Thanks,

David.

PS, Let me know if the photos don't turn out. I think I can fix that.

I'm sure I can't help you ID the ammo, but I can tell you that I can't view the pics

Those are 6.5X52mm Carcano. Case length 2.067" with an overall length of 3.012". No mystery.

Hi

I wish I could get a full picture of just one round.

If it's rimmed, it may be 6.5mm x 54mm Mannlicher-Schoenauer.
