The Federal Premium Freight Train 20 gauge copper sabot slug is a lead-free, high-velocity big-game load built around a 275-grain copper projectile with a polymer tip and externally skived expansion cavity. Designed for both rifled and smooth-bore barrels, this 3-inch shell generates 1900 feet per second at the muzzle with 2204 foot-pounds of energy — delivering flat trajectory and deep penetration from 50 to 200 yards. The proprietary sabot aligns the slug concentrically within the bore and separates cleanly at the muzzle, enabling sub-4-inch groups at 200 yards when fired through a rifled choke tube or rifled barrel. Federal Premium engineers the Freight Train for hunters who need non-toxic compliance without sacrificing terminal performance on deer, black bear, or wild hogs.
Built for the Box
The copper slug’s aerodynamic nose profile and boat-tail base reduce drag across the flight envelope, maintaining velocity and energy downrange. The externally skived cavity opens reliably across a broad impact-velocity window — from close shots inside 30 yards to extended ranges beyond 150 yards — without fragmenting or over-penetrating. Boxer primers seat in reloadable brass hulls with roll crimps; five rounds per box ship with DOT hazmat handling. Federal Premium manufactures this ammunition in the United States.

The Freight Train sabot slug fits smoothbore barrels with improved-cylinder or rifled choke tubes, as well as fully rifled slug barrels. For maximum accuracy, zero at 50 yards and verify point-of-impact at 100 and 150 yards before the season opener.

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 the muzzle pointed in a safe direction at all times.
- Verify state and local regulations regarding lead-free ammunition requirements for the hunting season and geographic unit where you plan to hunt.
- Store slugs in factory packaging until use; inspect each round for dents, corrosion, or loose primers before loading into the chamber.
