Sierras new 175 gr Tipped GameKing is designed to be tough and used for heavy duty hunting work. It will hit like a hammer on big game from the great 270 Winchester as well as be right at home in any magnum cartridge. It will use a 1-8 or faster twist rate to stabilize because of its long length but the BCs are also extremely high because of that. The higher BCs make it very efficient in flight so it will give a high impact velocity at distance. This bullet requires a barrel twist rate of 18 or faster. - Diameter (inches): 0.277 - Weight (grains): 175 Gr. - Sectional Density: 0.326 - Ballistic Coefficients and Velocity Ranges: .560 @ 1900 fps and above .530 between 1570 and 1900 fps .485 @ 1570 fps and below
