The proven efficiency and precision of Federal Premium makes this all-copper bullet a top choice for both target shooters and professional marksmen alike. One-piece design features a pressurized powder for rapid ignition. Expansion is controlled by the boat tail’s large hollow-point tip, ensuring consistent, large wound cavities, even with less-than-perfect accuracy. One-piece design also retains almost 100 percent of its weight. This .30-30 Winchester ammo‘s grooved bullet shank improves accuracy and allows it to penetrate deeply. The grooved base of the .30-30 cal bullet also improves its ability to expand upon impact. The design of the carrier itself is grooved, allowing it to roll or tumble more easily in the magazine. Nearly 100 percent weight retention means nearly 100 percent weight transfer upon impact. The all-copper, pressurized case is designed to reduce fouling, and its light weight keeps shooting at a high rate without weighing the shooter down.
