Brass case, copper or copper plated steel jacket, green over white tip, headstamp is “LC 93”. I do not know if the headstamp contains the NATO cross in it or not, as I am relaying second hand information and the pic I have seen is of the cartridge only, not the headstamp. This cartridge was also reportedly linked 1:10 with ball ammunition. The color code on the tip is that of the M-160 Frangible load, but the projectile material is wrong. The tip color also looks authentic, not “faked”. I’m thinking that this is one of the “Starlight” tracers maybe?
