The excellent ballistic performance makes it an ideal choice for shooting practice and serious competitions. It is manufactured by several brands including Federal Ammunition, Federal American Eagle Cartridge, Fiocchi Cartridges, Hornady, Winchester, CCI Blazer Rounds, and Remington.

As the construction is identical, 38 Special Ammo can be used in handguns chambered for 357 Magnum. 38 Short Colt and 38 Long Colt can be fired safely from handguns chambered for 38 Special. The straight walls of the cartridge, rim’s head spacing, accessibility of earlier fired cases, and the compatibility with 357 Magnum firearms made it much popular.
