The 38 Super, 9mm, 45 ACP, and 40 S & W races are extremely good for AUTO COMP. The perfect burning speed for supplying a higher volume of gas to the compensators. It’s a winner with AUTO COMP contestants taking faster shots with the minimal flash muzzle.
Since the late 1800s, there have been Winchester Smokeless Powders. Customers who shot loaded ammo in Winchester know that propellant quality is provided once the first shot is fired. Bring that quality home with the powder family of Winchester. For competing pistol shooters, AutoComp is the preferred powder. AutoComp powder can be used in many other pistols cartridge recettes with a superb performance in 38 Super, 9mm Luger, 40 S&W, and 45 ACP.
