The Buffalo Bore Buffalo-Barnes .357 Magnum 140-grain Barnes VOR-TX XPB Lead Free (Buffalo Bore part no. 19I20) is loaded to the pressures serious shooters expect from this small Montana company, not the watered-down velocities of mass-market factory ammo. This round is part of the Buffalo-Barnes series, pairing Buffalo Bore’s hot-rodded pressures with a lead-free Barnes bullet, built around Barnes’ all-copper XPB hollow point, which opens to roughly double its original diameter while retaining essentially all of its weight. Buffalo Bore hand-inspects every batch and loads with quality brass cases and clean-burning powder to keep pressures consistent from box to box. It’s a strong choice for shooters who carry, hunt, or train with .357 Magnum and want a load that actually performs at the pressures printed on the box.

Key Specifications

• It’s chambered in .357 Magnum, so it runs in any firearm built for the standard factory cartridge.
• The 140-grain bullet weight sits toward the lighter end for the caliber, which shapes both recoil and penetration depth.
• The bullet is Barnes XPB construction: it’s Barnes’ all-copper XPB hollow point, which opens to roughly double its original diameter while retaining essentially all of its weight, and expands on impact rather than driving straight through.
• This is part of the Buffalo-Barnes series, pairing Buffalo Bore’s hot-rodded pressures with a lead-free Barnes bullet.
• Cases are brass, which reloaders can resize and reuse, and which feeds reliably in both revolvers and lever guns.
• It ships 20 rounds to a box, sized for range trips and practical carry rotation.
• A full case runs 12 boxes (240 rounds), the volume option for shooters who train or carry this load regularly.
• Buffalo Bore’s box price works out to about $2.14 per round, in line with other premium hard-use ammunition.
• Buffalo Bore loads and pressure-tests every batch in-house in Montana rather than outsourcing to a mass contract loader, which is why the velocities hold consistent box to box.
