Barnes TSX Bullets .35 cal .358" 225 gr FB 50/ct

The Barnes TSX .35 cal 225 gr rifle bullet is a solid-copper, all-copper construction round designed for hunters pursuing medium to large game. These .358" diameter bullets combine controlled expansion with weight retention—delivering the bone-breaking penetration and reliable one-shot performance that serious reloaders count on in the field. Whether you're handloading for a .358 Winchester, .350 Remington Magnum, or similar cartridge, the TSX delivers the kind of terminal performance that separates a clean harvest from a wounded animal.

Built from 100 percent copper, the TSX is engineered to expand on impact into four razor-sharp petals that cut deep through hide, muscle, and bone alike. The bullet's construction ensures it retains its full original weight through the entire wound channel—no fragmentation, no lost effectiveness at distance. This weight retention is what makes the TSX a favorite among hunters who refuse to compromise on lethality or rely on luck.

Like all premium handloading components, seating depth matters. Barnes recommends starting with an off-the-lands seating distance of 0.03 to 0.07 inches and working up in your specific rifle to find the accuracy sweet spot. This box of 50 gives you plenty of rounds to develop a solid hunting load without breaking the bank on components. The 225 grain weight sits in the sweet spot for .35 caliber hunting rifles—heavy enough for deep penetration on thick-bodied game, but still fast enough to retain velocity at typical hunting ranges.

If you're serious about reloading, the TSX bullets' pure copper construction means consistent feeding and chamber fit. No jacket separation, no surprises at the moment of truth—just solid, repeatable ballistics from component to component.

Frequently Asked Questions

What rifles will these .35 caliber bullets work in?

The .358" diameter is used in .35 Whelen, .350 Remington Magnum, .358 Winchester, and similar .35 caliber rifle cartridges. Always verify your specific rifle's bore diameter before loading to ensure proper fit and accuracy.

Do these bullets come loaded in ammunition, or are they just components?

These are reloading components only—bullets for handloading. You'll need powder, primers, and cartridge brass to complete your ammunition.

Will the TSX bullets expand reliably on all game sizes?

Barnes designed these for expansion and deep penetration on medium to large game. The 225 grain weight and copper construction provide consistent, controlled expansion across typical hunting ranges and velocities.

What seating depth should I use?

Barnes recommends starting with a distance of 0.03 to 0.07 inches off the lands. The exact best seating depth is rifle-specific, so you'll need to load and test in your gun to dial in maximum accuracy.
