Barnes Bullets
If you're handloading for a .458 rifle and want bullets that deliver deep penetration and controlled expansion on hard-running game, the Barnes Triple-Shock X (TSX) 500 grain hollow point is built for the job. These lead-free rifle bullets are engineered from 100 percent copper, making them a solid choice for hunters in lead-restricted areas or those simply preferring non-traditional ammunition. The TSX design creates four razor-sharp petals on impact, combining aggressive tissue damage with the weight retention you need for consistent performance through bone and vital organs.
The flat-base configuration aids in consistent seating and feeding through most .458 rifles. Barnes states that best accuracy typically comes when seating these bullets between 0.03 to 0.07 inches from the rifling, though your specific rifle may prefer a different jump—test and find your sweet spot on the range. At 500 grains, this is a heavy, deep-penetrating option designed for medium to large game where follow-up shots may not be an option and energy retention matters.
Each box contains 20 bullets, enough for load development or a hunting season's worth of carefully prepared rounds. Because these are component bullets, you'll need to source your own brass, powder, and primers to complete your handloads. If you're running a .458 and want copper-based projectiles known for bone-breaking performance and 100 percent weight retention, the TSX is worth working up loads for.
