For turkey hunters running .410 bore shotguns, the Federal Heavyweight TSS 410 closes the gap between gauge and gobbler. This 3-inch shell loads 13/16 oz of #9 tungsten alloy shot — pellets built from an 18 g/cc tungsten-iron-nickel alloy that outweighs standard tungsten by 22% and lead by 56%. At 1100 fps muzzle velocity, each pellet retains more energy downrange, extending your effective pattern beyond what lead or steel can deliver in this bore diameter. Federal Premium engineers this load with advanced shot-cushioning buffer material and a full-length wad that shields your barrel from the extra-hard tungsten, preventing scoring while maintaining pattern density. A roll crimp and clear card wad lock the buffer in place during ignition. The result: tighter clusters at 30+ yards, more pellets on target, and cleaner kills on spring longbeards.

The 18 g/cc density translates to smaller pellets carrying more mass per pellet than lead #5 or #6. Pattern density stays tight through full and extra-full chokes; Federal recommends testing your specific choke/barrel combination at 20, 30, and 40 yards to map your effective range. A portion of proceeds supports the National Wild Turkey Federation. Browse more turkey-ready loads in our Federal 410 Ammo category.
Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Treat every firearm as if it is loaded; keep muzzle pointed in a safe direction at all times.
- Verify barrel obstruction and correct ammunition before firing; mismatched shells can cause barrel damage.
- Know your target, what is behind it, and what is between you and it; pellets can ricochet off hard surfaces.
