Take a look at the bottom of the primer pocket. Does it look to be bowed?
If your swaging backup rod has a small rounded tip, you may have bowed the bottom of the primer pockets.
Also, ballistic tools makes a primer pocket gauge. I set my swaging up then try a few with the gauge to see if the swaging setup is right. Then adjust if necessary.
