I have two starline .500 S&W mag cases, but what is the meaning of the third star in the centre of the line on one of them. These are (obviously) both brass cases.
The headstamp of one is:
— 500 S&W MAG R
and the second is:
--* 500 S&W MAG
I presume the “R” on the first stands for “Revolver”, but what is the meaning of the extra star on the second?
