Gun or Ammo?

[Crawdog]

I took my new Taurus Tracker 41 Magnum to the range today, taking along both PMC and Federal Premium ammo. Every one of the fired PMC cases needed to be pulled (and I mean pulled ) from the cylinder. The ejector rod pushed them out no farther that about 1/4 inch. The Federal cases were not nearly as hard to pull out, but they still would not eject with the rod. My questions now are, is PMC ammo just inferior ammo?; if so, how to explain the Federal Premiums?; or do I have a handgun with cylinder holes that are incorrectly sized? Any help on this is appreciated.
