Barnes TSX Bullets .458 cal .458" 450 gr FB 20/ct$37.11
Availability: In Stock
Barnes TSX bullets in .458 caliber deliver the controlled expansion and weight retention that serious hunters demand for dangerous game and heavy-hitting rifle applications. These .458" 350-grain solid copper projectiles are engineered to expand on impact while retaining 100 percent of their original weight—a critical advantage when you need deep, reliable penetration through bone and dense tissue. Built from pure copper construction, TSX bullets are known for producing four razor-sharp petals that cut aggressively through vital zones, making them a go-to choice for reloaders who prioritize one-shot reliability on large game.
The .458 TSX is particularly valued by hunters working with large-caliber rifles where shot placement and penetration matter most. The flat-base design offers straightforward seating, and Barnes recommends adjusting your seating depth between 0.03 and 0.07 inches depending on your specific rifle to maximize accuracy. This fine-tuning approach pays dividends at the range and in the field, where precision loading can mean the difference between a clean harvest and a lost opportunity.
Each box contains 20 bullets, giving you a practical quantity for load development, practice, or building a solid stock of ammunition for your next hunting season. Whether you're loading for a .458 Lott, .458 Win Mag, or another .458 platform, these copper bullets will perform consistently if you take the time to work up a load that your rifle prefers.
| Caliber | .458 | |
| Bullet Diameter | .458" | |
| Weight | 350 grains | |
| Construction | Solid copper | |
| Base Type | Flat base (FB) | |
| Quantity | 20 per box | |
| Recommended Seating Depth | 0.03–0.07 inches (rifle-dependent) |
These bullets are designed for .458-caliber rifles, including .458 Lott, .458 Win Mag, and similar large-bore platforms. Verify bore diameter and case capacity with your rifle's specifications and reloading manual before loading.
Seating depth affects how the bullet engages the rifling and influences accuracy. Every rifle prefers a slightly different depth, so Barnes recommends this range as a starting point. Work up your loads carefully, beginning at the longer distance and incrementally shortening until you find your rifle's sweet spot.
Yes—Barnes TSX bullets are engineered to retain 100 percent of their original weight on impact, which means no fragmentation and maximum penetration, especially important for large game and heavily boned animals.
Each box contains 20 bullets, providing a practical quantity for load testing, practice, or building your ammunition inventory.
