38 Super Ammo
The .38 Super or .38 Super Automatic (C.I.P. designation) is a pistol cartridge that fires a 0.356-inch-diameter (9.04 mm) bullet.
The Super was introduced in the late 1920s as a higher pressure loading of the .38 ACP or .38 Auto. The old .38 ACP propelled a 130-grain (8.4 g) bullet at 1,050 ft/s (320.0 m/s). The improved .38 Super Auto pushed the same 130-grain (8.4 g) bullet at 1,280 ft/s (390.1 m/s).
The .38 Super has gained distinction as the caliber of choice for many top pistol match competitors; it remains one of the dominant calibers in IPSC competition.
