No, 2 light strikes are not acceptable that is why I do not shoot matches with that ammo, practice only . I have had those light strikes with both my G34 and CZ Shadow. Mixed range brass, S&B, Winchester, and CCI primers. I blame my reloading setup. I believe I sorted it out by now and I have not had any light strikes for a while. Still I would shoot matches with Federal primers only because I have never had light strikes with Federal primers.
