First fail-to-fire with the federal (up to about 400 rounds of the 550 pack). It looked like a massive glob of primer was blocking the firing pin. No problem on 2nd try. I'm not holding this against the ammo. The remington gold never fails to dissapoint. 60 round through my pistol and at least 4 primer fire issues. I'm going to wally world asap to buy a few more packs of the federal 550 (load type 750 FWIW).
