Igman is good ammo. Igman and PPU were the two former factories producing ammunition in former Yugoslavia. I shot Igman 80s production m67 ammo and it worked great. From what I observed, Igman m67 had purple or pink primer sealant while ppu used red or orange sealant. On another note about Igman, I bought couple of cases of Igman 55 grain fmj .223 last year and the shooting performance was like any other fine brass case 223. I will say the appearance of the brass was much better than lake city winchester. I trust Igman over Turkish ammo.
