Buffalo Bore 500 S&W Mag 440gr Gas Checked Lead Flat Nose Ammo

Buffalo Bore Ammunition 18B20 delivers maximum stopping power for the .500 S&W Magnum platform with precision-engineered 440-grain gas checked lead flat nose projectiles. This heavy-hitting defensive ammunition transforms the massive .500 S&W cartridge into a formidable personal protection round capable of penetrating barriers while delivering devastating terminal performance.

What Makes This Different

The gas check design prevents lead fouling while maintaining accuracy at magnum velocities, addressing the primary weakness of traditional cast lead bullets in high-pressure applications. Buffalo Bore's proprietary powder selection generates consistent velocities around 1,625 fps from 8.375-inch barrels, producing over 2,580 foot-pounds of muzzle energy. The flat nose profile creates larger wound channels than rounded bullets while ensuring reliable feeding in revolvers.

Key Features

• 440-grain gas checked lead flat nose bullet for maximum energy transfer
• Optimized powder charge delivers 1,625 fps velocity with consistent performance
• Gas check prevents barrel fouling at magnum pressures
• Flat nose design creates devastating wound channels
• Premium brass cases built for multiple reloading cycles
• 20 rounds per box with 12 boxes per case for bulk purchasing
• Manufactured to SAAMI specifications for reliable chambering

Field testing demonstrates exceptional accuracy from quality revolvers, with groups under 3 inches at 50 yards from proper shooting positions. The heavy bullet weight maintains velocity downrange while the flat nose ensures immediate energy dump upon impact. Weather-resistant primer sealing prevents moisture infiltration during extended storage periods, making this ammunition suitable for duty carry and hunting applications where reliability cannot be compromised.
