Fiocchi Aero Extrema 12 Gauge 2.75-inch Rifled Slug ammunition (part no. 12FLRSLU) loads a single 1-ounce lead slug for shotgun hunters and self-defense shooters who need one hard-hitting projectile instead of a pattern of shot. Fiocchi has manufactured ammunition in Italy since 1876 and loads this slug to a full-power specification with the energy needed to cycle a semi-automatic shotgun action reliably. The rifling machined into the slug’s body imparts spin as it leaves a smooth-bore barrel, stabilizing the projectile in flight for the accuracy a slug-gun hunter or defender needs at shotgun ranges. In our shotgun shells lineup, this is the load for hunters and shooters who need one decisive hit rather than a spread of pellets.

Key Specifications

• The gauge is 12 Gauge, matching the great majority of pump and semi-auto shotguns already in the field.
• The shell length is 2.75 inches, the standard chamber length this slug is built to run through.
• This is a rifled slug, a single lead projectile rather than a pattern of shot pellets.
• The rifling cut into the slug’s body imparts spin, stabilizing it in flight for accuracy from a smooth-bore barrel.
• The payload weighs 1 ounce, concentrated into a single hard-hitting projectile instead of spread across dozens of pellets.
• Fiocchi loads this to a full-power specification, generating enough energy to reliably cycle a semi-automatic shotgun’s action.
• Each box holds 10 rounds, sized for a slug load meant for hunting or defense rather than high-volume shooting.
• A case ships 8 boxes (80 rounds total), useful for stocking up ahead of slug season.
• At about $17.40 per round, the price reflects precision slug construction rather than a birdshot field load.

Frequently Asked Questions

Is this a hunting or a self-defense load? Both — Fiocchi loads this full-power rifled slug for shotgun-only deer hunting as well as home-defense use, where a single decisive hit matters more than a shot pattern.

Will this cycle a semi-automatic shotgun? Yes, it is loaded to a full-power specification with enough energy to reliably cycle a semi-auto shotgun’s action, not just pump and break-action guns.

Why is a rifled slug more accurate than a smooth slug? The rifling cut into the slug’s body imparts spin as it leaves a smooth-bore barrel, stabilizing the projectile in flight the same way a rifled barrel stabilizes a bullet.
