Barnes Tsx Bullets .375 Cal .375" 350 Gr Fb 50/Ct

The Barnes TSX .375 caliber rifle bullet is a solid-copper hunting round built for the serious big-game reloader who demands reliable, deep-penetrating performance in a medium-bore magnum. At 350 grains, this flat-base projectile combines the stopping power hunters expect from a .375 with controlled expansion and weight retention—two qualities that separate ethical one-shot kills from wounded animals and long tracking jobs. Whether you're handloading for African plains game, elk at distance, or other large game where penetration through bone and heavy muscle matters, the TSX delivers consistent results shot after shot.

The TSX design starts with 100 percent copper construction, which means no jacket separation or core-jacket failures. On impact, the bullet expands into four razor-sharp petals that cut a devastating wound channel while the shank continues driving deep. That combination of reliable expansion and straight-line penetration is why the TSX remains a favorite among magnum rifle handloaders who refuse to compromise on terminal performance. The flat-base design seats cleanly in most .375 chambers and holds tight in the case.

As with all handloading components, accuracy depends on your specific rifle, powder charge, and seating depth. Barnes recommends testing seating depths between 0.03 and 0.07 inches from the rifling to find your rifle's sweet spot. Each box contains 50 bullets—enough to develop a load and put rounds downrange with confidence. If you're building ammunition for a magnum rifle and want a bullet that will perform when it counts, the Barnes TSX is a time-tested choice.

Specifications

Frequently Asked Questions

What rifles and calibers are these bullets designed for?

The Barnes TSX .375 bullets are engineered for .375-caliber rifle chambers. Always verify that your specific rifle's chamber and bore dimensions match the bullet specifications before loading.

Will these bullets penetrate heavy bone and dense muscle?

Yes. The 350-grain TSX is designed to penetrate bone and tissue while expanding into four cutting petals. Barnes rates these bullets for deep, reliable penetration on large game, and they retain 100 percent of their original weight—meaning no core or jacket loss during the wound channel.

What seating depth should I use in my .375 rifle?

Barnes recommends seating these bullets 0.03 to 0.07 inches from the rifling, but the optimal depth depends on your individual rifle's chamber and bore. Start at the longer distance (further from the lands) and work backward in small increments while chronographing and testing for accuracy.

How many bullets are in a box?

Each box contains 50 TSX bullets, enough to develop a complete load, verify accuracy, and have practice rounds on hand.
