Buffalo Bore 500 S&W Magnum ammo loaded with the 375-grain Barnes XPB solid hollow point is built for hunters who need deep penetration and lead-free compliance in the field. The 500 Smith & Wesson Magnum is one of the most powerful production handgun cartridges available, and Buffalo Bore loads it to full SAAMI specification — 1700 fps muzzle velocity and 2406 ft-lbs of energy from a revolver barrel. The Barnes XPB (X-Bullet Pistol) uses an all-copper construction that sheds no lead fragments, expands reliably across a wide velocity window, and retains nearly 100% of its weight through bone and tissue. This is serious game medicine for hog, bear, or any large animal where quick, humane stops matter and lead-free zones apply.
Built for the Box
Buffalo Bore manufactures this load in small batches to SAAMI maximums, meaning it is intended for modern, strong-frame revolvers only — not older or weaker designs. Each 375-grain Barnes XPB bullet features a solid copper shank with a hollow point cavity engineered to expand into six sharp petals on impact, creating a wide wound channel while maintaining straight-line penetration. Muzzle velocity of 1700 fps from a revolver barrel translates to flat trajectory and hard-hitting terminal performance at hunting distances. The load uses new brass cases with non-corrosive boxer primers, making once-fired brass ideal for reloading if you want to tailor your own loads. Lead-free construction meets hunting regulations in California and other jurisdictions that restrict traditional lead projectiles.
