I received some 308 brass from a friend, and after cleaning and sizing it, I have a question hopefully someone has the answer to.
Several of them have what looks like small "tread marks" around the outside of the case, down close to the case head. What does this mean, and are they ok to shoot?
I'll paste in a picture of this.
