Barnes TSX Bullets .338 Lapua .338" 285 gr BT 50/ct

The Barnes TSX .338 Lapua Magnum 285-grain bullet is a solid copper rifle bullet engineered for hunters pursuing large game at extended range. Built from 100 percent copper rather than traditional lead-core construction, the TSX delivers the controlled expansion and weight retention that serious reloaders demand when accuracy and terminal performance both matter.

On impact, the TSX's design initiates expansion into four razor-sharp petals that cut deep into vital areas while the bullet retains its full original weight throughout the wound channel. This combination of controlled expansion and complete weight retention is what sets copper-based ammunition apart for penetration through heavy bone and dense tissue—critical factors when one shot is the only opportunity. The .338 Lapua Magnum platform itself is proven for long-range hunting and precision shooting, and loading TSX bullets gives you the terminal ballistics to match that capability.

Each box contains 50 bullets ready to seat. For best accuracy with your rifle, Barnes recommends seating depth between 0.03 and 0.07 inches from the lands—a range you'll want to work through during load development to find your individual firearm's sweet spot. Whether you're handloading for a bolt-action hunting rifle or a specialized long-range platform, the TSX delivers the precision and reliability that define modern copper bullet performance.

Frequently Asked Questions

What rifle platforms use .338 Lapua Magnum 285-grain TSX bullets?

The .338 Lapua Magnum is a premium long-range hunting and precision rifle caliber used in bolt-action hunting rifles and specialized match rifles. Check your rifle's manual or chamber specification to confirm it's chambered in .338 Lapua Magnum before loading these bullets.

Why choose solid copper bullets like TSX instead of lead-core ammunition?

Solid copper bullets expand in a controlled, predictable manner and retain 100 percent of their weight, which means deeper penetration and more consistent performance through bone and muscle. This makes them a preferred choice for hunters pursuing large game where reliable expansion and penetration both matter.

What seating depth should I use when handloading TSX bullets?

Barnes recommends seating depth between 0.03 and 0.07 inches from the lands, but the exact depth varies depending on your individual rifle's chamber and throat. You should develop your load by working through this range to find the depth that produces the best accuracy in your specific firearm.

Are these factory-loaded rounds or reloading components?

These are component bullets sold for handloading only. You'll need to have the equipment, knowledge, and supplies to reload ammunition safely, including a reloading press, powder, primers, and brass cases.
