Win any competition with Federal Action Shotgun rifled slugs. The hulls' rigidity improves cycling through both tube- and magazine-fed shotguns, for fast, reliable performance when fractions of a second mean everything. The proven Federal TruBallA(R) system uses a polymer sphere nested in the base of the slug to center the projectile as it travels down the barrel, for unmatched accuracy through smoothbores. The 1-ounce rifled slug is pushed out the muzzle at 1,300 fps, providing the power needed to knock down targets as well as manageable recoil.
