Barnes TSX bullets in .458 caliber deliver the controlled expansion and deep penetration that large-game hunters need for ethical, effective shots. These 450-grain solid copper projectiles are engineered to create four sharp-edged petals on impact while retaining 100% of their original weight—critical performance when you're pursuing elk, moose, or African game at distance. Built from pure copper construction, TSX bullets resist barrel fouling and deliver consistent ballistics across your reloading runs, making them a reliable choice for precision rifle cartridges like the .458 Winchester Magnum or other .458-based builds.
What sets the TSX apart is the combination of controlled expansion and weight retention. Those four cutting petals do serious work through bone and tissue, creating a wound channel that doesn't rely on explosive fragmentation. For hunters who reload their own ammunition, that reliability translates to confidence in the field. The flat-base design seats easily, and Barnes recommends seating depth between 0.03 and 0.07 inches depending on your specific rifle—a range that gives you tuning room to dial in accuracy for your platform.
Each box contains 20 bullets, giving you plenty for load development and a full season in the field. Whether you're working up loads for a new rifle or restocking your reloading bench, these copper solids represent serious stopping power in a premium bullet that hunters trust for one-shot performance.
