Winchester WinClean 244 is a modern double-base spherical (BALL) handgun powder introduced to provide clean-burning, low-flash performance across a wide range of popular pistol cartridges. Its burn rate is similar to Winchester 231/HP-38, making it well suited for standard-pressure 9mm Luger, .38 Special, .40 S&W, and .45 ACP target and defensive loads. The fine spherical granules meter exceptionally well through progressive powder measures, ensuring consistent charge weights. WinClean additives reduce copper fouling and airborne lead while leaving less residue in the firearm. Although versatile and economical, W244 is intended for medium handgun loads rather than full-power magnum revolver cartridges.
