Barnes TSX Bullets .45/70 .458" 250 gr FN 20/ct

Barnes TSX Bullets .45/70 .458" 250 grain flat nose ammunition delivers controlled expansion and maximum bone-penetrating performance for big game hunting and large-frame rifle applications. Constructed from 100 percent copper with no lead core, these monolithic bullets expand on impact to create four razor-sharp petals while retaining 100 percent of original weight—a critical advantage for deep penetration through dense bone and tissue in one-shot scenarios.

The 250-grain weight in the .458" diameter is engineered for the .45/70 Government cartridge, balancing velocity retention with the power delivery expected from this classic big-bore rifle caliber. The flat nose profile provides reliable feeding in lever-action and modern single-shot platforms while the solid copper construction eliminates core-jacket separation—a failure mode that compromises energy transfer on heavily muscled game. Barnes TSX ammunition is loaded in 20-round boxes, allowing shooters to verify reliability and accuracy through their specific rifle before committing to field use.

This load is suited for hunters using .45/70 rifles—whether lever-action carbines like the Marlin 1895 or modern single-shot platforms—pursuing elk, moose, bear, and other large species where deep penetration and controlled expansion are non-negotiable. The monolithic bullet design tolerates a wider range of impact velocities than traditional cup-and-core designs, making it effective across hunting distances where velocity variation becomes a factor. Shooters should always verify point-of-impact and terminal performance through their specific rifle before field deployment.

The .45/70 Government remains one of North America's most effective large-game hunting cartridges, and barrel-length-appropriate ammunition like TSX loads maximizes its potential. Barnes ammunition is loaded to conservative pressure levels, ensuring safety across a wide range of .45/70 rifles from both vintage and contemporary manufacturers.
