Chinese special headstamp from factory "61"



The special headstamp is founded on 5.56mm and 5.8mm,which is mark the caliber on the headstamp,I got four cases with this headstamp,three of them are produced in 2000,and one of them is produced in 2003,this headstamp is really interesting,I wonder if there are some other cartridge cases with this headstamp.
