Ramshot powders are double-based, spherical-shaped, smokeless powders that meter easy, burn clean and produce high velocities. Excellent lot-to-lot consistencies for repeatable accuracy between loads. True Blue performs extremely well in progressive reloaders where consistent charge weights are required. Recommended for .380 Auto to .454 Casull including 9mm, .38 Special, .357 Mag, and .45 ACP. Mfg: Ramshot Powder
