Hornady Superformance .257 Roberts +P Ammo 117gr SST 20 Rounds

Increase your rifle's performance up to 200 fps without extra chamber pressure, muzzle blast, temperature sensitivity, or fouling with the HornadyA(R) SuperformanceA(R) 257 Roberts +P 117gr SSTA(R). This centerfire rifle ammo is loaded in premium brass casings with clean-burning powders and propriety Superformance propellants, paired with premium components and Hornady's boattail Super Shock TipA(R) (SST) bullet for dependable ignition, super-flat trajectories, and smooth operation in virtually any hunting environment. The hard polymer tip is designed to drive deep into the bullet on impact to initiate lightning-fast, yet controlled expansion for lethal penetration on medium-sized game. Plus, Hornady's InterlockA(R) ring locks the core and jacket together to help the bullet maintain its form for longer ensuring maximum weight retention on impact. Further, Superformance ammo is up to 200 fps faster than conventional ammunition with uncompromising accuracy without increased felt recoil. For optimal results with a gas-operated semi-auto firearm, it is recommended that all Hornady Superformance ammunition be paired with rifle-length gas systems and barrel lengths of 20" or longer. Any barrel and gas configuration of less than 20" is best served with the installation of an adjustable gas system, especially if firing suppressed. Made in USA.
