AutoComp Powder
Winchester AutoComp Powders have been around since the late 1800s. Customers that have shot Winchester factory loaded ammunition know that quality of propellant they’re receiving as soon as the first shot is fired. Bring that quality home to the reloading bench with the Winchester family of powders.
Winchester AUTOCOMP is a ball powder designed for competition race guns. A perfect burn speed to feed the compensators with a higher volume of gas, it is a great choice for 38 Super, 9mm, 45 ACP and 40 S&W. With AUTOCOMP, competitors get off faster shots with minimal muzzle flash.
Other Important Information:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
