Forget what you think you know about smoothbore slug gun accuracy. The Federal Premium TruBall is the most consistent smoothbore slug on the market, capable of groups as tight as 1.4 inch at 50 yards. The TruBall system locks the components together, centering and pushing the rifled slug out of the barrel. This promotes clean separation of components after muzzle exit to ensure the best accuracy.A plastic ball between the wad and slug increases smoothbore accuracyCapable of 1.4-inch groups at 50 yardsClean separation of components after muzzle exitIncreased downrange energySpecificationsGauge 12 GaugeBullet Weight 438Muzzle Velocity 1300Bullet Style TruBall Hollow Point SlugType SlugShot Charge Oz 1Shotshell Length 2-3/4in. / 70mmBallistic Coefficient .070Package Quantity 5Usage Medium Game
