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 1x14" twist rates stabilizing easily for excellent long-range accuracy and effective expansion. Normally 1x12" 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.
