Hornady Superformance SST Ammunition 257 Roberts +P 117 Grain SST Polymer Tip Box of 20

Loaded with Hornady’s InterLock Super Shock Tip (SST) bullet, this round combines proven Hornady performance with a higher ballistic coefficient than available with most hunting bullets. The sharp, pointed polymer tip creates a faster, flatter shooting bullet. With its one-piece core and jacket strengthened in critical areas, the SST delivers much more controlled expansion and superior weight retention than other tipped bullets. Featuring Hornady’s trade mark InterLock ring system, this bullet’s core and jacket remain locked solid during expansion, creating massive wound channels.
