I just found an unknown can of 7.62x54r in my basement. I opened it as the markings were gone. In it are 20 wedge shaped boxes each holding 15 rds on clips. I couldnt read the headstamp. It looks like a 3 digit number at 12 oclock and a single digit at 6 oclock. Any idea what it is? Guy I bought it from said it is Chinese. Very excited as I now have some clips.
