The Barnes TSX (Triple-Shock X) is a .375-caliber, 350-grain flat-base rifle bullet (Barnes part no. 30494) machined from 100% copper. On impact it expands into four razor-sharp petals with deep-cutting capability while the solid shank retains nearly all of its original weight, giving hunters the one-shot penetration they rely on when dense bone and heavy tissue stand between the bullet and the vitals. At 350 grains, this is the heavier option in Barnes’ .375 TSX lineup, built for hunters who prioritize penetration on the biggest, toughest game. Each box holds 50 bullets.
