7.62x51mm tear gas (CS), two peice brass construction, top with grey tip, 2nd half is copperwashed, with lead filler and bottom. Brass cased. Headstamp - can not read/4-61, Israelee? All cartridges have 4-61, but box says 5-61. Comes on strippers and 20rds in a box. Got a little contaminated with this one! (kevin)
Yes, Israeli, and I believe that all known examples are 4-61.
