IIRC, the federal law does not use the word "felony"; it says "convicted of a CRIME punishable by more than one year in jail." In most states, misdemeanor pushishment is less than one year, but the federal law specifies one misdemeanor (domestic abuse) that also bars firearms possession. (The word "possession" is used rather than "ownership" to get past arguments like "the gun isn't mine, a friend left it here.")
