Winchester AutoComp Powder

Winchester logo

Winchester AUTOCOMP is a ball powder intended for use in competition race guns. A superb choice for 38 Super, 9mm, 45 ACP, and 40 S&W, with a proper burn speed to feed the compensators with a bigger amount of gas. Competitors use AUTOCOMP to fire faster shots with less muzzle flash.

Since the late 1800s, Winchester Smokeless Powders have been available. Customers who have shot Winchester factory loaded ammunition know the grade of propellant they are getting from the first shot. Bring that quality to your reloading bench with the Winchester powder family.

For competitive pistol shooters, AutoComp is the recommended powder. AutoComp powder, which performs admirably in the 38 Super, 9mm Luger, 40 S&W, and 45 ACP, can also be utilized in a variety of other handgun cartridge designs.
