308 head stamp?

[Red hunter]

Has anyone seen a CBC head stamp? Is this brass any good? can it be reloaded at least 4 times? I have found several hundred of them but I have not seen this stamp before and unsure about buying them. Any input would be apreciated. The boxes are loaded ammo it saya made in brazil. No bullet weight marked on box. Just has 7.62x51 CBC and a lot number.

Depends on when it was made. In the mid '70's several lots had a mix of pistol and rifle powder. I can't even imagine those results................Newer stuff seems ok but the necks apparently are soft and prone to splitting. I wouldn't shoot it but that's just me. Oh, it says it 147gr ball fmj.
