Winchester Powder AC1 Ball Powder AutoComp Smokeless Pistol 1 lb

The Winchester AutoComp is a smokeless ball powder purpose-built for competition race guns and compensated pistols. Formulated to deliver a higher volume of gas at the right burn speed, AutoComp keeps compensators fed and running cleanly through long strings of fire on the line.

AutoComp is ideally suited to popular pistol calibers used in action-pistol and race-gun disciplines, including the 38 Super, 9mm Luger, 40 S&W, and 45 ACP. Its fine-grained ball powder construction meters consistently through progressive presses, helping reloaders turn out accurate, repeatable loads round after round.

This listing is for a single 1 lb container of Winchester AutoComp smokeless pistol powder. Whether you are loading major-power-factor 38 Super for USPSA, pushing compensated 9mm Open division rounds, or building clean-shooting 45 ACP match ammo, AutoComp is designed to keep up with the demands of competition use.
