Barnes Tipped Triple-Shock X (TTSX) Bullets 284 Caliber, 7mm (284 Diameter) 140 Grain Spitzer Boat Tail Lead-Free Box of 50

Barnes Tipped Triple-Shock X (TTSX) bullets in 284 caliber are purpose-built for hunters who demand reliable, hard-hitting performance on big game. These 140-grain, 7mm lead-free projectiles combine a modern polymer tip with Barnes' proven copper construction to deliver consistent accuracy and devastating terminal performance—making them an excellent choice for reloaders committed to ammunition that performs as hard as you hunt.

The polymer tip serves dual duty: it boosts the ballistic coefficient for flatter trajectories and extended effective range, while also promoting controlled, rapid expansion on impact. When these bullets strike, the copper body splits into four sharp-edged petals that expand roughly 50 percent in diameter, creating a larger wound channel and maximizing energy transfer through vital organs. This expansion geometry is what makes the TTSX earn its reputation for quick, ethical kills on deer, elk, and other medium-to-large game.

Built entirely from copper rather than traditional lead-core construction, TTSX bullets deliver superior accuracy and are compliant with lead-free hunting regulations in states and regions where such ammunition is required. Reloaders working up loads for 284-caliber rifles should plan for seating depth between 0.030 and 0.070 inches off the lands—the exact distance will depend on your specific rifle's chamber and throat geometry, so load development and pressure testing remain essential.

Whether you're handloading for a 7mm Remington Magnum, 284 Winchester, or similar cartridge, these 50-round boxes give you the foundation for hunting ammunition that's accurate, ethical, and built to perform when it matters most.

Frequently Asked Questions

What rifles and cartridges are these 7mm bullets best suited for?

These 140-grain, 284-diameter TTSX bullets are intended for 7mm rifle cartridges such as the 7mm Remington Magnum, 284 Winchester, 7mm-08 Remington, and other standard 7mm chambers. Always verify that your specific rifle's chamber and twist rate are appropriate for the bullet weight and design before assembling ammunition.

Are these bullets legal for hunting in all states?

These are lead-free copper bullets, which makes them compliant with non-toxic ammunition requirements in states and regions where lead ammunition is prohibited. However, ammunition regulations vary by location and game type—check your local hunting regulations before purchasing and loading.

What's the recommended seating depth for reloading?

Barnes recommends seating these TTSX bullets between 0.030 and 0.070 inches off the lands, depending on your individual rifle's chamber specifications and throat geometry. You'll need to measure your rifle and perform load development to determine the optimal seating depth for accuracy and pressure.

Do I get 50 bullets per box?

Yes, this is a box of 50 bullets, giving you the raw material for 50 complete rifle rounds once you've added cases, primers, and powder.
