When I'm not shooting high dollar Eley red box, I buy some Winchester Dynapoints in a bulk pack from Kmart ($12.99/500) for practice. I've had the same experiences with the Federals that you did. I've also had the similar experiences with Winchester T-22, Remington Standard Velocity Target for failing-to-fire (FTF) in several different target pistols. I do get a few FTF's with the Dynapoints but its much less than the others.
