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

The 296 powder developed for the 357 Magnum and 44 Remington Magnum cartridges. Winchester also recommends this propellant for use in 410 Bore AA loads..
