The Barnes Triple-Shock X (TSX) Bullets in .505 Gibbs, 525 grain flat base (brand part no. 30688), give dangerous-game hunters a monolithic-copper option built for a one-shot kill on the largest game. Barnes machines the TSX line from 100 percent copper, and the design is engineered to expand on impact into four razor-sharp petals with deep cutting capability while retaining 100 percent of the bullet’s original weight. Barnes states best accuracy is typically found when seating the bullet between 0.03 and 0.07 inch off the lands, depending on the rifle. For a caliber like .505 Gibbs, built specifically for the largest and most dangerous game on the planet, that combination of full weight retention and controlled expansion is exactly what hunters need.
