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 Winchesterfamily of powders.
Do not exceed the loads displayed in the reloaders guide.
Never mix any two powders regardless of type, brand, or source.
Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
