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 Winchester family of powders.
The 296 powder was developed for the 357 Magnum and 44 Remington Magnum cartridges. Winchester also recommends this propellant for use in 410 Bore AA loads.
This propellant was developed for Winchester factory-loaded ammunition for 357 Magnum, 444 Magnum, and 410 Bore. Its high loading density provides optimal velocity. 296 is recommended by Winchester for 410 Bore AA loads.
In 1929, the Western Cartridge Company (forerunner of Winchester Ammunition) received U.S. Patent #2,027,114, issued to Western Cartridge as “Manufacture of Smokeless Powders.” Shortly after, Western Cartridge Company then commercially introduced BALL POWDER® smokeless propellant. The innovative BALL POWDER® process provided a number of technological advantages over common extruded type powders that were quickly leveraged by ammunition factories and the U.S. military. The key advantages of BALL POWDER® propellant include:
• Stable long life – in some cases exceeding the capability of extruded powders
• High density – ideal for rifle calibers. Yet the BALL POWDER® process is capable of density adjustment to also create high-performance pistol and shotshell powders
• Adjustable chemistry – allows the powder to be tailored to specific cartridge applications through chemistry as well as geometry.
• Lower flame temperature – allows longer barrel life
