Description Federal Premium designed the Vital-Shok Slug TruBall system to make the smoothbore 12 gauge shotgun slug more effective for the standard slug slinger.Federal's Vital-Shok 12 gauge 2.75" shell fires a 1 ounce rifled slug at 1300 fps, making it a good choice for animals with tough hide and bone such as hogs, deer and bear. The low-recoil rounds are favorable even for youth hunters. It's also a great choice for home defense. TruBall Deep Penetrator cartridges contain a plastic ball between the wad and slug to center the slug in the barrel, as well as a harder (higher antimony) lead than the standard TruBall. Now you can upgrade your power without changing barrels or sacrificing accuracy.PRODUCT DETAILFederal Vital-Shok 12 Gauge Ammunition 250 Rounds 2 3/4" Rifled Slug 1 oz Caliber: 12 Gauge Shell Length: 2 3/4" Shot Type: Rifled Hollow Point Slug Shot Weight: 1 Ounce Rounds: 250 Round Case Muzzle Velocity: 1300 fps Muzzle Energy: 1773 ft/lbs Low Recoil Plastic ball between the wad and slug increases smoothbore accuracy Capable of 1.4-inch groups at 50 yards Clean separation of components after muzzle exit Increased downrange energy Deep Penetrator slugâs higher antimony lead ensures better terminal performance on hogs and bears Firearms, trailers, and some accessories are only available for purchase in stores.
