Description

Winchester AutoComp is a high-performance spherical pistol powder engineered specifically for competitive shooting and compensated race guns. Designed with an optimized burn rate that produces increased gas volume, AutoComp helps compensators function more efficiently for flatter shooting and faster follow-up shots.

Ideal for action shooting disciplines and high-speed competition setups, Winchester AutoComp delivers reliable ignition, clean-burning performance, and consistent velocities in popular handgun cartridges such as .38 Super, 9mm Luger, .45 ACP, and .40 S&W. Its spherical powder design meters smoothly through progressive presses, making it an excellent choice for high-volume reloaders seeking precision and efficiency.

AutoComp is also formulated to minimize muzzle flash, helping shooters maintain visibility and control during rapid-fire stages and low-light shooting conditions. The combination of consistent pressure curves and optimized gas production makes it a trusted choice for serious competition shooters.
