Some questions nCBC headstamps

Please, help me with these two CBC headstamp:
What is it TREINA? Ammunition for training with reduced charge?
What is a meananing of “C V” letters in 38 SPL headstamp?

Treskin - “Treina” is a form of the Portuguese word equal to “Training” in English. I think I saw somewhere what the CV on the .38 meant, perhaps on this Forum, but I can find it. Many times said, I can’t find anything, ever, using the search engine on this Forum.

By the way, if anyone ever finds one of these CBC Treina .40 cal rounds, I NEED ONE!

Treshkin, “Treina” stands for Treinamento, which means “Training” in Portuguese language, as already mentioned by John. It is loaded with a 160 gr lead bullet and was introduced in 2004 as a low cost law enforcement training cartridge. It was also made in .357 Magnum, .38 Special, .380 Auto, .45 Auto and 9 mm Parabellum. The propellant charge is not reduced.

We discussed the “C V” marking here: viewtopic.php?f=8&t=15423



Thank you very much!

Has anyone got an image of the TREINA headstamp in 9mmP???
