Whatever, if it's NATO (North Atlantic Treaty Organization) it will be crimped in primer so you'll have to remove the crimp no matter what. Dillon makes a dandy crimp remover for a hunderd bucks and RCBS makes a crimp remover tool for hand use about 15 bucks. I chuck 'em in a larhe with a turret tailstock and use a countersink.
