P.O. Ackley favored short .30 caliber magnums and called it "highly recommended." Performance with a 150-grain (9.7 g) bullet is up to 3,590 ft/s (1,090 m/s), with a 180-grain (12 g) bullet is up to 3,200 ft/s (980 m/s) and with a 220-grain (14 g) bullet is up to 2,705 ft/s (824 m/s). [24]

The original plan was to market the .40 Super as the .40 SIG, the big brother to the .357 ...
