The Barnes TSX .375 caliber 270-grain flat-base bullet is a solid-copper hunting projectile built for reloaders who want dependable expansion and the kind of penetration that drives straight through heavy bone. With no lead core to separate or come apart, this bullet holds together on impact and pushes deep, which is exactly what you want when you're putting a big animal down cleanly. It carries a .375 diameter, a sectional density of .274, and a ballistic coefficient of .326.
The magic is in the construction. Being 100 percent copper, the TSX retains close to all of its original weight and opens up into four razor-sharp petals that double the frontal diameter. That combination of deep penetration and a wide wound channel is why hunters lean on it for tough, thick-skinned game. Barnes built the TSX to cut roughly a quarter deeper than traditional lead-core bullets, and the all-copper body means it won't fragment and lose mass the way a cup-and-core bullet can.
The multiple grooves cut into the bullet shank are the defining feature of the Triple-Shock X design. Those rings act as relief valves as the bullet travels down the bore, which cuts down on pressure, reduces copper fouling, and helps you chase tighter groups. In a .375 H&H or .375 Ruger, the 270-grain weight is a sweet spot. It runs with noticeably less recoil than a 300-grain load while still handling just about anything from plains game up through larger North American game, and plenty of handloaders call it their do-everything .375 bullet.
This is a reloading component only, not loaded ammunition. For best accuracy, Barnes recommends starting with the bullet seated off the lands and working loads up from there, with most rifles printing their tightest groups somewhere in the .030 to .070 inch range.
It's a big game hunting bullet that shines in .375 caliber cartridges like the .375 H&H and .375 Ruger. The all-copper build and deep penetration make it well suited for elk, moose, bear, and African plains game. Many hunters consider the 270-grain weight a true do-everything .375 load.
Yes. The TSX is made from 100 percent copper with no lead core at all, so it won't fragment or shed its core on impact. That solid construction is a big part of why it retains nearly all of its weight and penetrates so deeply.
Barnes suggests starting the bullet seated off the lands and then fine-tuning from there. Most rifles will print their best groups somewhere in the .030 to .070 inch off the lands range. It's worth testing a few seating depths to find the sweet spot in your specific barrel.
They do. The rings cut into the bullet shank act as relief valves as the bullet moves down the bore, which lowers pressure and reduces copper fouling. That cleaner, more consistent trip through the barrel is a big reason the TSX has a reputation for strong accuracy.
