Barnes TSX 45-70 Government 250 Grain Rifle Ammunition

Barnes TSX (Triple-Shock X) ammunition in 45-70 Government features bullets with all-copper construction designed to resist fragmentation. The TSX delivers 28% deeper penetration compared to lead core bullets and maintains maximum weight retention through impact. The bullet design incorporates multiple, precisely engineered rings cut into the shank that function as relief valves during barrel travel, improving accuracy, reducing pressures for higher velocity loads, and minimizing copper fouling.
