Buffalo Bore 45 Auto Rim +P 255gr Hard Cast FN Ammo - 20 Rounds

The Buffalo Bore 32A20 delivers maximum stopping power in the classic 45 Auto Rim cartridge, loaded with a 255-grain hard cast flat nose bullet at +P pressures. This premium defensive ammunition transforms vintage revolvers and modern firearms into formidable defensive tools with deep penetration and reliable expansion.

What Makes This Different

Unlike standard 45 Auto Rim loads that barely exceed cowboy action velocities, this +P configuration pushes the 255-grain hard cast bullet to velocities approaching 900 fps from a 5-inch barrel. The flat nose design creates larger wound channels than round nose alternatives while the hard cast construction ensures consistent performance through barriers. Buffalo Bore's reputation for maximum-pressure loads means this cartridge extracts every bit of potential from the 45 Auto Rim case.

Key Features

• 255-grain hard cast flat nose bullet for deep penetration and tissue disruption
• +P pressure loading generates approximately 850-900 fps velocity
• Compatible with 45 Auto Rim chambered revolvers and converted firearms
• Hard cast construction resists deformation through heavy clothing and barriers
• Flat nose profile creates larger permanent wound cavity than round nose designs
• Premium brass cases sized for reliable extraction and feeding
• 20 rounds per box, 12 boxes per case for 240 total rounds

This ammunition excels in defensive scenarios where penetration through heavy clothing or light barriers is critical. The flat nose hard cast bullet maintains its shape and weight retention even after impacting bone or other obstacles. Revolvers chambered in 45 Auto Rim benefit from the increased velocity and energy compared to standard pressure loads, while the consistent powder charge ensures reliable ignition and accuracy.
