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. TAC produces high velocities with 80 grain bullets in the .223 caliber while maintaining SAAMI pressure guidelines. Ideal for 223 Rem and .308 Win. This is the benchrest favorite of the Ramshot line. Works great in PPC and BR cartridges. Mfg: Ramshot Powder
