Description
Federal Premium brought back the immensely popular Barnes Triple-Shock X for hunters who want a proven, purpose-built cartridge they can trust. This load pairs 140-grain all-copper Barnes bullets with Federal's precision manufacturing and quality components to create ammunition that's ready to work straight out of the box.
Why 7mm-08 Rem 140gr Works for Hunting
The 7mm-08 has become a favorite among folks who refuse to compromise on performance but want mild recoil, flatter trajectories than heavier cartridges, and a rifle that won't beat them up during a long hunt. The 140-grain weight sits right in the sweet spot for medium game. At 2820 feet per second muzzle velocity and 2472 foot-pounds of energy, this load carries enough power to ethically take deer out to several hundred yards, yet it remains manageable to shoot. This cartridge excels on whitetail and mule deer, and remains effective on elk when you do your part with shot placement.
Barnes Triple-Shock X Bullet Construction
The TSX bullet is engineered differently than typical jacketed rounds. Its monolithic all-copper design retains nearly 100 percent of its weight on impact, which means you get both deep penetration and consistent expansion. The hollow point opens predictably, and the grooved shank reduces barrel fouling while improving accuracy. This solid design translates to repeatable performance from one shot to the next, which matters when you're counting on one opportunity.
Factory Precision You Can Count On
Each round is loaded to strict specifications with reloadable, nickel-plated brass cases and quality primers. Federal's standards mean the ammunition feeds reliably in most hunting rifles and delivers the accuracy you've worked to develop. The consistency from round to round builds confidence when it matters most.

Frequently Asked Questions
What kind of game is the 7mm-08 Rem with a 140-grain bullet suitable for?
The 7mm-08 with this 140-grain load is ideal for deer and is effective on other medium-sized game. It's mild on recoil and has a flatter trajectory than many other hunting cartridges, making it popular for hunters of all sizes. While it can work on larger game like elk with proper shot placement, it's best suited to medium game where the controlled expansion of the Barnes TSX really shines.
How far can you effectively shoot the 7mm-08 Rem 140gr Barnes TSX?
For deer hunting, this load remains effective out to 400-500 yards with the right setup and clean shot placement. The high ballistic coefficient of the TSX bullet helps it maintain velocity and energy downrange. Your personal skill, barrel length, and zero will influence your actual effective range, so practice at the distances you hunt.
What makes the Barnes Triple-Shock X bullet different from other hunting bullets?
The TSX is a monolithic all-copper bullet rather than a traditional jacket-and-core design. It retains nearly 100% of its weight on impact, giving you both deep penetration and reliable expansion. The grooved shank reduces fouling and improves accuracy. This combination of penetration and consistent expansion is what makes it a trusted choice for hunters across various calibers and game types.
Are these rounds reloadable?
Yes, the nickel-plated brass cases are reloadable using standard reloading techniques. The Boxer primers are also a standard type that works with reloading equipment. If you're a handloader, this ammunition can provide good brass for building more loads down the road.
