Sounds like crimped primers to me.

You may have to swage or chamfer the primer pocket if they were crimped primers.

If it looks like the brass was pressed around the original primer, you can use a couple of turns of a chamfer tool to remove the crimp before seating the new primer.
 
Yup, Federal uses a ring type crimp. As they mentioned, a quick pass wih your chamfer tool will remove it. Or buy a RCBS or Dillon swage tool.
 
Yep, you have crimped primers. All the suggestions on how to remove the crimp are already stated above. I had a 550 at one time and had a primers go off while seating them a couple times. When I called Dillon about it they told me not to use Federal primers. I stopped using the 550 to prime and never had a problem after that.
