A red-lacquered case head indicates a proof load.
The case should also have a silver-grey appearance. SAAMI recommends all proof load casings be tin-plated.

You can reload them, but you need to keep in mind that the cases experienced a minimum of a 30% over-pressure (over maximum allowable pressure).
