7.62x51 NATO Blank?

Is this a Spanish blank? Without books yet it’s hard for me to find… thanks as usual!

Probably a Short-range Training round, rather than a Blank.
For indoor target practice.
Doc AV

Roger that, makes sense… thanks!

Yes DocAV is right, it’s a short range for training.

Thanks Rigby. Is there a recommended publication you recommend for non-US NATO cartridges?

My pictures are from the book of Molina-Orea “cartoucheria espanola”.

“Die Militärpatronen Kaliber 7,62 x 51 mm NATO” by Brandt, Kamann, Kaltmann, and Kiehn.
It is however not very easy to get a hold of, and somewhat outdated by now.
