Flat and hard. I do not worry much about expansion. I shoot a real hard alloy, water dropped, and double powder coated, flat points for pistols and rifles, with a plain base. Big hogs and bears take penetration with good accuracy both.
“To expect defeat is nine-tenths of defeat itself. It becomes a self-fulfilling prophecy. It is best to plan for all eventualities then believe in success, and only cross the failure bridge if you come to it." Francis Marion - The Swamp Fox
