The Barnes TSX (Triple-Shock X) is a .375-caliber, 300-grain boat-tail rifle bullet (Barnes part no. 30491) machined from 100% copper rather than a traditional lead core and jacket. On impact, the design expands into four razor-sharp petals for a wide, deep-cutting wound channel while the solid-copper shank retains virtually all of its original weight for reliable penetration on tough, heavy game. Barnes lists this bullet at a sectional density of 0.305 and a ballistic coefficient of 0.357, giving handloaders the ballistic data needed to build a flat-shooting, dependable .375 load. Each box holds 50 bullets.
