Barnes TSX 458 Caliber 500 Grain Rifle Ammunition

Barnes TSX (Triple-Shock X) ammunition in .458 caliber delivers 500-grain projectiles built with all-copper construction that won’t fragment and penetrates 28% deeper than lead core bullets while retaining maximum weight. The TSX bullet incorporates multiple precision-engineered rings along the shank that function as relief valves during travel down the bore, yielding improved accuracy, reduced pressures for higher velocity loads, and less copper fouling.
