Federal
Federal primers are my first choice. A few of my rifles are fairly accurate and Federals are what most benchresters use, I believe. The only primers I've ever actually had trouble with were CCI large pistol primers.
In my S&W 29, 8grs. of Unique with 250 gr. hard cast LSWC's, I was getting pierced primers. Checked the firing pin and everything else I could think of. This is just a .44 Special load in a magnum case (I doubt that its more than 15,000 psi).
Anyway when I switched to Federal large pistol primers, the problem disappeared. Probably just a soft batch of those CCI's, but it was enough to make me switch.
