A can shell includes a center panel. An inclined panel wall extends at a downward angle from the center panel. An annular countersink is formed around the inclined panel wall and includes an inner countersink wall and an outer countersink wall. A countersink base is formed at a bottom end of the inner countersink wall and a bottom end of the outer countersink wall. A chuck wall extends from the outer countersink wall. The inner countersink wall and the outer countersink wall are generally parallel between the countersink base and the inclined panel wall and the chuck wall. A curl extends radially outwardly from the chuck wall. The countersink has a depth of between 0.265 and 0.280 inches from the uppermost surface of the curl and a depth of between 0.085 and 0.11 inches from the center panel.
