The Federal Premium Vital-Shok 20 Gauge 3" TruBall HP Rifled Slug delivers the kind of accuracy from a smoothbore shotgun that used to require a rifled barrel. If you've relied on smoothbore slugs for deer or other medium-to-large game hunting, you've probably accepted some inherent shot-to-shot variance—but the TruBall system changes that equation. This is engineered ammunition designed to group tighter and perform more consistently than conventional slugs, giving shotgun hunters the precision they've traditionally sacrificed for the simplicity of a smoothbore platform.
The secret is the TruBall's component-locking design. A specialized plastic ball seats between the wad and the rifled slug itself, centering and aligning the projectile as it travels down the barrel. This geometry promotes clean separation of the wad and ball immediately after the slug exits the muzzle, eliminating the tumbling or deflection that plagues standard slugs. The result is tighter, more predictable shot placement out to practical hunting ranges.
Federal engineered these rounds specifically for smoothbore shotguns, so if you're running a standard 20-gauge barrel without rifling, the Vital-Shok TruBall is the ammunition that bridges the accuracy gap. Each box contains five rounds ready to load—a practical quantity for range testing and field use. Whether you're sighting in before the season or taking the shot that counts, consistent performance matters, and that's what this load delivers.

The TruBall is specifically designed for smoothbore shotgun barrels. The component-locking and ball-separator system is engineered to function in a standard smoothbore, not a rifled slug barrel. Always confirm your barrel type before purchasing.
These rounds are loaded for 3-inch chambers. Your shotgun must be chambered for 3-inch 20-gauge ammunition. Check your owner's manual or chamber marking—loading a 3-inch round in a 2.75-inch chamber is unsafe and can cause damage or injury.
Federal's testing indicates the TruBall system is capable of consistent groups at 50 yards. Actual field accuracy depends on your barrel, sights, shooting technique, and ammunition batch, but the TruBall design is engineered to deliver tighter groups than conventional smoothbore slugs.
These are loaded under the Federal Premium Vital-Shok line, which is purpose-built for hunting medium-to-large game. The slug weight and energy profile are designed with that application in mind.
