Winchester AutoComp is specifically formulated for competitive pistol shooters demanding fast, clean, and consistent performance. Known for its superior performance in race guns and compensated pistols, AutoComp delivers optimal gas pressure to enhance compensator function while minimizing muzzle rise and flash.
This powder excels in popular competition calibers like .38 Super, 9mm Major, .40 S&W, and .45 ACP, making it a go-to choice for USPSA, IPSC, and steel challenge shooters.
