Federal Barnes Tsx Rifle Ammunition .300 Win Mag 165Gr 3050 Fps 20/Ct

The Federal Barnes TSX rifle ammunition in .300 Win Mag is built around Barnes's proven monolithic copper bullet design—a favorite among hunters and long-range shooters who demand reliable terminal performance in demanding conditions. This 165-grain load launches at 3050 feet per second and combines deep penetration with consistent, wide expansion, making it well-suited for medium to large game at extended distances where shot placement and bullet integrity matter most.

What sets the Barnes TSX apart is its one-piece copper construction. Unlike traditional lead-core bullets, the solid copper design retains nearly 100 percent of its weight on impact, meaning less mass lost to fragmentation and more energy transferred downrange where it counts. The deep hollow-point tip initiates expansion reliably across a range of velocities and impact angles, while the grooved shank design does double duty: it reduces copper fouling in your barrel and tightens groups by improving how the bullet engages the rifling.

Federal's quality control and consistent loading make these rounds reliable across multiple shots, which matters when you're dialing in at distance or counting on repeat shots in the field. The 20-round count per box gives you enough to work up a load, verify zero, and still have rounds for the hunt. If you're pushing your .300 Win Mag hard and want a bullet engineered for penetration without excessive barrel fouling, the Barnes TSX delivers the kind of performance that backs up its reputation.

Frequently Asked Questions

What makes Barnes TSX bullets different from standard rifle bullets?

The TSX is a one-piece copper bullet rather than a traditional lead-core design. It retains nearly 100 percent of its weight on impact, which means deeper penetration and less fragmentation. The grooved shank also reduces copper fouling in your barrel and can improve accuracy.

Is Federal Barnes TSX ammunition suitable for hunting?

Yes. The .300 Win Mag loaded with 165-grain TSX bullets is designed for hunters pursuing medium to large game. The consistent expansion and deep penetration make it effective at extended ranges where the .300 Win Mag's ballistics shine.

What's the velocity of these rounds?

Federal loads this ammunition to 3050 feet per second from a rifle with a standard-length barrel, which delivers the ballistic performance the .300 Win Mag is known for.

How many rounds come in a box?

Each box contains 20 rounds, giving you enough to develop a load, verify your zero, or have on hand for hunting trips.
