Federal Premium Power-Shok . Winchester 170 Grain Jacketed Soft Point Centerfire Rifle Ammo 20 Rounds. Popular bullets like the bonded Sledge Hammer InterLock and NTX give shooters the terminal ballistics they need to take down everything from prairie predators to hogs and wild boars. Federal takes lead out of the equation by starting with a dependable boat-rock solid base. The jacketed soft point provides the expansion and energy efficiency that shooters need and a non-corrosive design that ensures the shooter can use this round in any weather conditions. A heavier bullet reduces lead use in some cases so shooters can reuse the ammunition.
