All bullet shapes in this classification are flat base, and they include round nose (RN), semi-pointed (SMP), spitzer-pointed (SPT), flat nose (FN), and with a hollow point (HP/FN). A few bullets in this category have Sierra’s proprietary Power Jacket to enhance bullet expansion in game animals when fired from medium-velocity cartridges. All these bullets have medium to heavy weights in each caliber, and they are designed for a combination of penetration and expansion in medium and heavy game animals for their calibers.
