The Barnes TSX (Triple-Shock X) is a homogeneous, 100% copper hollow-point bullet for reloaders working in .375 calibre, supplied 50 to the box at 350 grains. Machined from a solid copper slug with no lead core or jacket to separate, the TSX retains close to 100% of its weight on impact, giving the deep, reliable penetration .375-calibre hunters loading for large plains and dangerous game rely on. The bullet's nose cavity opens on contact and peels back into four sharp-edged copper petals, delivering controlled expansion to roughly double calibre diameter across a broad range of impact velocities, from close range out to longer shots. Multiple precision-cut rings around the bullet shank act as pressure-relief grooves, reducing bearing surface against the bore; this lowers chamber pressure and virtually eliminates copper fouling, while helping the load reach higher velocities safely. The reduced bore friction also underpins the TSX's reputation for tight groups from a handloaded round. Being lead-free, it is legal for use where lead ammunition is restricted. A dependable choice for anyone handloading .375 ammunition who wants deep penetration and controlled expansion without core-jacket separation.
