For rifles this is a high-velocity bullet designed to give precision accuracy with the explosive expansion of Sierra’s Varminter-style construction. This bullet is at its best when fired from the larger-capacity cartridges such as the 22-250 or 220 Swift in rifles with barrels having 1×14 twist rates stabilizing easily for excellent long-range accuracy and effective expansion. Normally 1×12 or faster twist rates work best for medium-capacity cases such as the 223 Remington. These bullets are excellent for long-range varmint hunting. - For handguns although this bullet is of Hollow Point construction we cannot recommend it for hunting purposes. This bullet has been very successful on half-size NRA Silhouette targets. - The #1375 was introduced in 1984. - Diameter (inches): 0.224 - Weight (grains): 60 Gr. - Sectional Density: 0.171 - Ballistic Coefficients and Velocity Ranges: .246 @ 2800 fps and above .240 between 2800 and 2000 fps .246 @ 2000 fps and below - Box Count: 100 Bullets
