Winchester AutoComp

Winchester^® AutoComp is a high-performance ball powder engineered specifically for competitive pistol shooters using race guns and compensated handguns. Known for its ideal burn rate and clean-burning characteristics, AutoComp is a preferred choice for action shooting sports like USPSA, IPSC, and Steel Challenge.

Designed to generate a high volume of gas, Winchester AutoComp is particularly effective with compensators, helping reduce muzzle rise and felt recoil. This makes follow-up shots faster and more accurate—critical advantages for competitive shooters looking to shave time between targets.

AutoComp is perfectly suited for calibers such as .38 Super, 9mm, .45 ACP, and .40 S&W. Its burn profile supports consistent cycling and pressure, which ensures reliable function in finely tuned competition pistols. In addition to top-tier performance, it produces minimal muzzle flash—a benefit when shooting in low light or indoor ranges where distractions from bright flashes can impair focus and visibility.

Another standout feature of AutoComp is its metering consistency. As a ball powder, it flows easily through powder measures and progressive presses, reducing charge variation and supporting precise load development. This reliability makes it ideal not just for high-speed matches but also for shooters who demand consistent results during training sessions.

Whether you’re building match-grade ammunition for a compensated open-class handgun or fine-tuning a load for carry optics, Winchester AutoComp delivers the gas volume, clean performance, and speed modern competitors require.

Available in 1 lb., 4 lb., and 8 lb. containers.
