The Barnes VOR-TX Safari .458 Lott 500 gr TSX FB is purpose-built for serious hunters who need ammunition they can absolutely rely on when facing dangerous game. This is the pairing that works: a magnum cartridge with serious case capacity paired with one of the toughest bullets Barnes makes.
What sets the TSX bullet apart is its all-copper construction and those precision-engineered relief grooves cut into the shank. When you fire, those grooves let the soft copper displace smoothly as it travels down the bore, which means lower pressures, less barrel fouling, and the ability to push these rounds to higher velocities safely. On impact, the hollow point peels back into four razor-sharp cutting petals that slice through bone and tissue while the bullet retains virtually all of its weight. You get dramatic wound channels and deep, straight-line penetration without fragmentation or deflection.
The .458 Lott cartridge was born from field experience. It solves the case capacity limitations of the shorter .458 Winchester Magnum by stretching to a full 2.8-inch case, which means you're not compressing powder charges and you're getting real velocity from heavy bullets. Factory specs for this particular load clock the 500-grain TSX at roughly 2200 fps out of the muzzle, delivering over 5300 foot-pounds of energy. That's the kind of down-range authority that keeps you in control when facing heavy, thick-skinned game in Africa or pursuing North American dangerous game.
The all-copper construction isn't just a feature, it's fundamental to how this bullet performs. Lead-free bullets maintain their structural integrity far better than traditional jacketed designs, which translates to consistent expansion and superior weight retention every single time. You get no core-jacket separation, no fragmentation that might drift off target, and clean exits that create proper blood trails.
You get 20 rounds loaded into new brass, ready to go. This is ammunition for hunters who understand that in dangerous game hunting, consistency and reliability aren't luxuries. They're survival.
The TSX is an all-copper bullet with relief grooves cut into the shank that reduce fouling and allow safer, higher velocities. When it expands, it creates four razor-sharp cutting petals while retaining nearly 100% of its original weight, delivering deep penetration without fragmentation. This construction provides both devastating terminal performance and excellent accuracy.
Yes. The .458 Lott has a longer case (2.8 inches vs 2.5 inches) that holds significantly more powder, which means you get better velocity with heavy bullets and avoid compressed powder charges. This translates to flatter trajectories, deeper penetration, and more reliable performance on dangerous game without excessive pressure spikes.
No. The .458 Lott is designed for rifles with a full-length magnum action (like the .375 H&H length). .458 Winchester Magnum rifles will not safely chamber .458 Lott ammunition. Always verify your rifle is specifically chambered for .458 Lott before loading and firing these rounds.
Copper bullets run slightly warmer than traditional lead-core bullets and require different powder selections, but the Barnes system with its relief grooves manages this smoothly. Most shooters find the improved accuracy, reduced fouling, and superior penetration well worth any minor load adjustments. These rounds are factory-loaded and ready to use without any guesswork.
