270 Winchester 140 Grain (SST) Super Shock Tipped Superformance 20 Rounds
By Hornady

Superformance ammunition is loaded with proprietary propellants that increase the velocity ratings up to 200 feet per second compared to other popular brands on the market. Because there is no increase in pressure, reguardless of the caliber, there is no increase in felt recoil but there is a significant increase in efficiency and high speed performance. From sub-zero arctic temperature to almost unbearable desert heat, Superformance ammo can withstand any hunting condition.

Loaded with Hornady's InterLock Super Shock Tip (SST) bullet, this round combines proven Hornady performance with a higher ballistic coefficient than previously available with most 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, the bullet's core and jacket remain locked solid during expansion, creating massive wound channels.
