For waterfowl hunters working marshes, rivers, and wetlands under federal non-toxic shot mandates, 20 gauge steel shot splits the difference between 12-gauge payload and true sub-gauge portability. The Fiocchi Flyway Series loads 7/8 oz of #4 steel pellets into a 3-inch hull, clocking 1500 fps at the muzzle — velocity that flattens trajectories inside 35 yards and delivers humane, quick kills on teal, wood ducks, and early-season mallards. The protective wad system shields your bore from steel-on-steel contact, and the reloadable Boxer-primed hull extends your range budget when you save empties.
Built for the Marsh
Fiocchi manufactures the Flyway Series with treated steel shot that resists corrosion when exposed to humidity, salt spray, and wet retrieves. The maximum dram equivalent powder charge pushes the 7/8 oz payload to 1500 fps — enough energy to penetrate feathers and down at typical over-decoy ranges without the recoil spike of a full 1-ounce load. The 6-point star crimp crimps consistently for smooth feeding in pump and auto actions, and the smooth-bore designation confirms compatibility with any choke from cylinder to modified.

| Gauge | 20 Gauge |

The #4 pellet diameter balances pattern density with individual pellet energy — appropriate for ducks from teal to pintail at ranges inside 40 yards. Fiocchi ships this load in 25-round boxes, and the protective wad minimizes bore wear when running hundreds of rounds through the same barrel during a season. You’ll find this steel load grouped with other lead-free options in our 20 Gauge Steel Shot 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; keep finger off trigger until ready to shoot; be certain of your target and what lies beyond it.
- Verify current federal, state, and local ammunition regulations — some jurisdictions restrict steel shot use by season or location; others mandate non-toxic loads year-round on public land and waterways.
- Steel shot is harder than lead and can damage chokes tighter than full; consult your shotgun’s manual before patterning this load through extra-full or turkey chokes.
