Winchester WinClean 244 Smokeless Gun Powder

Winchester Smokeless Powders have been around since the late 1800s. Customers that have shot Winchester factory loaded ammunition know that quality of propellant they’re receiving as soon as the first shot is fired. Bring that quality home to the reloading bench with the Winchester family of powders.

Winchester WinClean 244 is a ball powder developed for medium handgun loads. It is ideally suited to 38 Special, 45 Auto, and 9mm standard loads. Consistency, low flash, and a broad range of applications make this powder a choice for any handgun cartridge loader. Since it is a ball powder, it features precise metering. And with the WinClean additive, this powder is cleaner burning and reduces copper fouling.

Precision Performance for Practical Loads

Winchester WinClean 244 is a modern, clean-burning propellant engineered to deliver reliable ignition and predictable velocities for many common loading applications. Designed with consistency in mind, WinClean 244 helps shooters achieve repeatable ballistics and tighter group-to-group performance whether you’re producing practice rounds, defensive carry ammo, or target loads. Always develop loads using official Winchester/Hodgdon data and start at recommended starting charges.

Cleaner Combustion Less Fouling, More Range Time

WinClean technology focuses on reducing carbon and copper deposits in barrels and actions. That means less frequent cleaning, improved semi-auto cycling reliability, and longer strings of accurate fire before maintenance is required. For instructors, range rats, and serious reloaders, the cleaner burn translates directly into more time shooting and fewer interruptions for scrubbing bores.

Smooth Metering & Reloading Efficiency

WinClean 244’s grain structure meters consistently through powder measures and performs well on both single-stage and progressive presses. That predictable flow reduces charge variance, speeds up batch production, and simplifies load development so you can rapidly produce uniform rounds with confidence. Its handling characteristics make it a pragmatic choice for hobbyists and high-volume reloaders alike.

Temperature Behavior & Real-World Reliability

Formulated for dependable performance across everyday temperature ranges, WinClean 244 provides stable ignition and predictable pressure behavior in normal field and range conditions. While no powder is completely immune to extreme temperatures, this propellant is built to keep point-of-impact shifts minimal during typical seasonal swings. As always, follow published load tables and safe reloading practices.
