Winchester spherical powders are known for their
consistent burn rates and clean burning characteristics
and are widely used for reloading shotshell,
handgun, and rifle ammunition. Useful for reduced velocity loads in 12 gauge 7/8 oz.
and 1-1/8 oz. loads. Great choice when assembling
light loads for younger or recoil-sensitive shooters.
