I pick up Federal primers when I can't find the usual preferences (CCI, Winchester, Magtech, Remington, Fiocchi, S&B, etc. ...in that order).
They work just fine. I've never had any problems or "anomalies" when using them. I just don't like the bulky packaging, and most of my loads have been worked up with CCI or Winchester primers. So, using the Federal primers means I have to run at least one string of pressure-testing loads.
