Big Federal box may be for more sentive primers.
Federal primers contain some Nitroglycerin. CCI does not. Check the sds, Safety Data Sheet of both/others.
Many years ago, the Lee Hand Primer had a warning, not to use federal primers. Lee redesigned it around 2010 . It was possible to set off the whole tray of primer, if when seating a primer, it jammed & was forced.
Keep this in mind when seating any primer. If it jams, dont force it.
