Bring that quality to your reloading bench with the Winchester powder family.The 296 powder was designed for use in the 357 Magnum and 44 Remington Magnum cartridges. This propellant is also recommended by Winchester for use in 410 Bore AA loads.

- 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.
