Barnes Pioneer .357 Magnum 140gr TSX Flat Nose – 20 Rounds

Barnes Pioneer .357 Magnum ammunition delivers all-copper bullet performance in a flat nose profile designed for tubular magazine rifles and wheelguns. The 140-grain TSX (Triple-Shock X) Flat Nose bullet expands reliably at revolver velocities while penetrating deep on medium game—ideal for lever-action hunters and backcountry defense loads. The solid copper construction ensures near 100% weight retention, creating wide wound channels without lead contamination in harvested game.

This load is compatible with all .357 Magnum revolvers and lever-action carbines chambered in .357 Magnum or .38 Special/.357 Magnum. Cases and primers are non-corrosive, boxer-primed brass suitable for reloading. Available in 20-round boxes or 200-round cases for range prep and hunting stockpiles.
