The Federal Premium Freight Train 12 gauge copper slug arrives as a lead-free saboted projectile engineered for rifled shotgun barrels and jurisdictions requiring non-toxic ammunition. Each 300-grain copper slug launches at 2000 feet per second with 2664 foot-pounds of muzzle energy from 3-inch magnum hulls. Federal Premium guarantees sub-4-inch groups at 200 yards when fired through properly maintained rifled barrels — precision uncommon in smoothbore-compatible loads. The polymer tip and aerodynamic ogive hold velocity through extended range, while the externally skived nose cavity delivers controlled expansion across impact velocities from 1400 to 2000 fps. Hunters tracking whitetail, black bear, or feral hog in lead-restricted areas now have a bonded-core alternative that maintains sectional density without shedding lead fragments.
Performance at a Glance
Federal Premium machines each copper slug from solid stock — no bonded cores, no lead trace, no jacket separation. The sabot aligns the projectile within the bore and releases cleanly at the muzzle, eliminating yaw that degrades accuracy past 100 yards. Boxer primers and roll-crimped hulls allow reloading for cost-conscious hunters who shoot volume during practice. The 300-grain weight sits in the midpoint of 12-gauge slug offerings — heavy enough for bone penetration, light enough to hold velocity at distances where whitetail become aware of movement.

Accuracy claims hold when paired with rifled barrels sporting fixed or adjustable sights — smoothbore tubes will stabilize the sabot but sacrifice the guaranteed sub-4-inch dispersion. Check your state’s slug regulations before ordering; some regions mandate rifled-only use for specific game seasons. Shop additional 12 gauge slugs for comparison across rifled and smoothbore platforms.
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.
- Always keep your muzzle pointed in a safe direction. Treat every firearm as if it were loaded.
- Verify that your shotgun is chambered for 3-inch magnum shells before loading — shorter chambers will not safely accommodate this load.
- This ammunition contains copper — verify compliance with regional non-toxic requirements, as some areas mandate specific alloy compositions beyond lead-free status. Proposition 65 warning applies due to trace lead in primers.
