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. Winchester Super Field is the best choice for Winchester 20 gauge AA target loads,
and may be used for maximum velocity in12 gauge 11/8 oz. and 1¼ oz. loadings. Also
performs well in semi-auto handgun loads like 9mm, 38 Super, and 40 S&W.
