I dont know about their .223 ammo, but i have used wolf ammo in my SKS and didnt care for it. I usually had at least 5 per box of 20 that didnt go off. I would buy a few boxes because they were really cheap and when i would start shooting several wouldnt fire. The primers were dented but they were duds, it has happened with every box of wolf that i have tried. I may just have bad luck with them, you should try and see if you have better luck.
