DESCRIPTION

257 Roberts +P 117 Grain (SST) Super Shock Tipped Superformance 20 Rounds
by Hornady Ammunition and Bullets


Superformance ammunition is loaded with proprietary propellants that increase the velocity ratings up to 200 feet per second compared to other popular brands of ammunition. Because there is no increase in pressure, reguardless of the caliber, there is no increase in felt recoil but there is an increase in efficiency and high speed performance. From arctic like temperatures to just about unbearable desert heat, Superformance ammunition can withstand any conditions while hunting.

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