Federal Premium 223 Remington 55 Grain Barnes TSX ammunition delivers the all-copper performance hunters and precision shooters trust for consistent, reliable results downrange. Built on a monolithic copper design, the Barnes TSX hollow point expands reliably across a wide range of velocities while retaining nearly all of its weight to drive deep into game without fragmentation or unpredictable deflection.
The Barnes TSX's grooved shank design does more than just look distinctive—it minimizes copper fouling in your barrel, which means cleaner shooting sessions and less maintenance between range visits. That attention to bullet construction also translates to tighter groups and improved accuracy, especially important if you're dialing in loads or shooting at distance. The deep hollow point combines with the solid copper construction for large-diameter, consistent expansion on impact, whether you're hunting varmints or deer-sized game.
This is centerfire rifle ammunition engineered for hunters who want performance they can count on without the complexity of premium pricing on every single round. Twenty rounds per box makes this a sensible choice for practice, load development, or stocking your hunting ammo box.
