Description
If you've ever wondered why this load keeps finding its way into hunters' ammunition lockers year after year, it comes down to the monolithic all-copper Barnes TSX bullet doing exactly what it promises. The 165-grain projectile is specifically engineered for the 300 Winchester Magnum's short magazine, with a tapered nose profile that delivers consistent long-range grouping without sacrificing terminal performance.
What Makes This Federal Premium Load Stand Out
Federal Premium pairs their full-house quality components with the Barnes bullet design you trust. That means rigorous primer inspections, premium clean-burning powders, and nickel-plated brass that resists corrosion and handles extraction smoothly in tough conditions. The Barnes TSX itself is a time-tested all-copper hollow point that sheds minimal fouling as it passes through your barrel, letting you shoot more before cleaning becomes necessary. On impact, the bullet's deep hollow point creates razor-sharp petals that expand to nearly double its original diameter while retaining its weight for deep, reliable penetration.
Ballistic Performance and Field Results
With a muzzle velocity of 3050 feet per second and 3408 foot-pounds of energy, this load delivers the velocity needed for consistent accuracy at distance while minimizing bullet drop in typical hunting scenarios. The grooved bullet shank reduces pressure and improves accuracy downrange. Real-world field reports consistently show one-shot, clean results on elk and deer, with the bullet's aggressive expansion and weight retention doing the job reliably at typical hunting ranges.
Box Contents
Each box contains 20 rounds of factory-fresh ammunition with full manufacturer identification and lot traceability. The nickel-plated cases are reloadable for those who handload their own ammunition.

Frequently Asked Questions
What makes the Barnes TSX different from conventional jacketed bullets?
The TSX is manufactured from solid copper with no lead core, creating a monolithic design that retains nearly 100 percent of its weight during impact. This weight retention, combined with its deep hollow point cavity that expands to nearly double its original diameter, results in consistent expansion and deep penetration without the fragmentation issues that can occur with traditional jacketed bullets.
Is the Federal Premium 300 Win Mag 165gr Barnes TSX suitable for long-range hunting?
Yes. The 165-grain weight and 3050 fps velocity create a flatter trajectory than heavier bullets while maintaining excellent accuracy at extended ranges. The grooved bullet shank improves accuracy downrange, and real-world hunting reports show consistent results from 200 to 300+ yards. For shots beyond 350 yards, consider the heavier grain weights Federal offers in this line.
How does the nickel-plated brass help with performance?
Nickel-plating on the brass cases offers two key benefits. It resists corrosion, which extends the usable life of the rounds during storage or in humid conditions. The nickel coating also provides smoother extraction from your rifle's chamber, which is especially valuable in extreme conditions or after extended shooting sessions without cleaning.
Can I reload the Federal Premium cases after firing?
Yes, the nickel-plated brass cases are reloadable. The cases maintain consistent dimensions for predictable reloading performance. However, nickel-plated brass typically requires softer reloading dies to avoid excessive wear on your equipment compared to unplated brass.
