Winchester Powder AutoComp 8lb

Winchester AutoCom

is a variety of gunpowder developed for use in high-pressure competition firearms. This ammunition is great for feeding gas into compensators and is available in 9mm, 45 ACP, and 40 S&W, so you won’t go wrong with any of those calibers. With auto-competition, shooters can reduce muzzle flash and increase their rate of fire.
