Barnes Pioneer 357 Mag 180gr Ammunition - 20 Rounds per Box (200 Rounds Total)

Barnes Pioneer 357 Magnum ammunition pairs the ballistic reliability of a classic revolver or lever gun round with modern bullet engineering designed for hunting and sport shooting. This 180-grain load delivers the stopping power that has made the .357 Magnum a trusted choice for decades—whether you're working with a traditional wheelgun, a lever-action rifle, or a modern carbine. The 200-round total (packaged as ten 20-round boxes) gives you a practical supply without breaking the bank or taking up a gun safe.

What sets Pioneer ammunition apart is the Barnes Original Bullet, engineered for controlled expansion and reliable weight retention on game. The combination of bullet design and proven powder charge creates predictable terminal performance across typical hunting and defensive distances. These rounds are built to feed reliably through tubular magazines found in many lever guns, and they cycle smoothly in revolvers—no special handling needed. You get consistent velocity and accuracy from box to box, which means less variation at the range and more confidence in the field.

Shooters choose Barnes Pioneer because it bridges the gap between nostalgic caliber and serious on-game performance. The .357 Magnum was never a compromise cartridge, and this ammunition respects that legacy. Whether you're bringing a vintage rifle out for a hunt, carrying a wheelgun as a backup, or practicing on the range, these rounds deliver the kind of terminal performance that justifies the time you spend training with them.
