brass question

[RodneyO]

Does anyone know what firearm, chamber or barrel makes these marks? I'm a curious cat.

It's from a fluted chamber. Some machine guns have these types of chambers.

And some semi autos have them as well.

CETME has a chamber like that. Get your small base dies and be prepared to scrap them. They would not be my first choice to reload.

Small base dies?

Small base dies?

You'll probably need them if you plan on using that brass
