Winchester AutoComp

Handgun

Burn Rate: 9 (Fast)

Description

Winchester AutoComp is a medium-fast burn rate propellant specifically tailored for handgun applications, ideal for competitive and recreational shooting. As a spherical powder, it offers excellent metering properties, ensuring consistent charge weights during the reloading process. This characteristic is particularly beneficial when producing large volumes of ammunition, as it minimizes variations in powder drop that can affect velocity and accuracy. AutoComp is engineered to deliver consistent performance across a wide range of temperatures, making it reliable in varying environmental conditions. This powder is renowned for its optimal use in calibers such as .38 Super, 9mm Luger, .40 S&W, and .45 ACP. Its formulation is designed to produce high velocities and low muzzle flash, key factors for practical shooting disciplines. Load development with AutoComp allows handloaders to achieve fine-tuned accuracy and performance, with ballistic consistency being a paramount feature. Winchester's reputation for quality and reliability assures loaders that AutoComp is a reliable choice for top-tier handgun reloading.
