Oleg,
I've got a couple of cans of either Yugo or Czech Aught-six and have sent many rounds down range through my Garand. No missfires with this weapon. Putting them through the Ruger M77 is a different story. Have had three that didn't go bang, even after snapping the round two or three times. These rounds are sitting off to the side, waiting for me to pull them down and replace the primers. Fair enough accuracy through the Garand though. The price was right at the time, I've no regrets
